Display Blocked

I have around 18 displays, 15 of which are using the same presentation and 3 which are not.  This week all of my displays started getting the "blocked display" error randomly.  We are using preconfigured Linux players that were purchased from Risevision in November 2014.    The presentations are fairly simple with a text scroller, a static jpg image, and some webm videos   using the "video item"  and Rise Storage.

Hi Kaleb,

Are the displays being blocked connected over wireless internet?

2 of them, yes, most are hard wired.

Kaleb,

Could you please see our documentation on display blocking? If you have followed these suggestions and are still seeing a problem, we will be happy to look further into the platform to see if there is a bug with display blocking. We also offer one on one support through support.risevision.com.

There are no known network issue.  I am able to maintain an active SSH session into these boxes.

I am attempting to purchase support, however at the shopping cart where I would expect to click "checkout" I get an error "error:  unknown error" in red.

Sorry to hear you are having trouble Kaleb.

Can you email store@risevision.com with the name of your Company and the user you are trying to purchase as? I'd like to see if I can determine why you are getting that error.

Thanks!

I am curious if this was ever resolved.  It seems a few weeks ago something blew up in the Rise system and we continually get blocked displays now in waves when we change nothing on our end.  
This reply was created from a merged topic originally titled Display blocked after about 4 hours.

We have a display, that appears to be blocked every time it has run about 4 hours.
The rise vision player is opened automatically every morning at 8 and shutdown every afternoon at 4.
The presentation runs on a raspberry pi 2B using linaro and chromium 41.

Link til presentation: http://preview.risevision.com/Viewer.html?type=presentation&id=87004d1a-59bb-4711-9767-1bdc52baa...

Could you please tell me what could cause this issue? We have looked at the memory usage on the raspberry, but that doesn't appear to be the issue.
Just to give an update, since last weeks changes, we are still seing the blocking, even though it now seems to be more random.

Libratone,

Thanks for the update. I'm going to play your content locally to see if I can replicate a block.

I don't know what to do...I'm out of ideas.  Occasionally we just come in to find a bunch of displays blocked.  Today is one such day.  We have done nothing different.  We have added no files, removed no files....but displays that we blocked at epidemic proportions a few weeks ran without incident after working with Blake and the team.  It just all blew up again this morning.

I wanted to add another comment to this to help show the whole picture and why we are having a hard time thinking it might be on our end.  WIth that one customer we are having display issues with, we have 3 types of screens...of the three One type has 16, one type has 7 and one type has 3.  Each one is EXACTLY the same within that type.  The one with 16 had 13 blocked...some were on the customer network, some were on wide open internet...connect right to the modem, nothing in the way.  Of the type with 3, one was blocked...two were working.  ...again...makes no sense.   The display type with 7 has no blocks.  I would say if the type with no blocks and 7 displays is the most simple, it might make sense that there was a memory issue...however, it's not.  It's the mid-level of the three.  It runs videos and jpgs and runs inside the customer's network, but others run outside the customer network to the wide open internet.  The type with 3...and one blocked, is the most simple.  It's just a website on a URL gadget.  The type with 13 blocked (most of them) is the most perplexing because it is the most complex.  However, EVERY single one of these is the same.  This is with the exception of a couple of machines in outlying areas that don't play all the files because of their geographic location.  Oddly, every single one of the machines that doesn't play all files was blocked, while the three that weren't blocked were in the region that plays all the files.  Also the ones not blocked are all inside the customer network while those being blocked were a combination of inside and outside the network.  I don't see how there is any logic that can be applied to any of this.

I have done significant work on this issue and discovered (at least in my case) that Windows boxes using either the native Riseplayer app or the Chrome App are not affected, however any of my non-windows (i.e. Linux) boxes are blocked very frequently.   Seems to me that there is some sore of bug somewhere in the rise ecosystem related to Linux players.

Kaleb,  Our experience has not been the same.  When we first encountered the issue we were instructed to change our machines over to the Chrome App.  It was at that point that the landslide of blocked machines began.  It is an interesting way to look at the issue though, because as I look at all our customers and all our machines, I don't think any of the native players on Windows are being blocked.  I'll have to look further into this.  Unfortunately though the native players caused another issue that was just as bad, so we can't use that for many of our applications either.  I am curious, on a side note, are you using any player with the Chrome OS?

Thank you.  We don't either.  I just wondered what type of luck people have had and if they were having this issue as well.

Would you guys mind checking the Chrome Version on the players that have been blocked, compared to the Chrome version on the players that are displaying content normally? Please let me know what you find.

Blake, It's hard to do a full complete research of this since the displays are all running in banks with 2 50" or 55" screens in the lobby.  However I did check 2 locations, one that was blocked and one that was not and both have the same version of Chrome - 42.0.2311.135m

So I'm an idiot.  Apparently I can find this info right in the Rise interface.  I did discover the only machine in this company that has never been blocked is not only not running the Chrome App, but also have a different version of Chrome than the two I mentioned...which actually may just add to the perceived randomness of the issue, other than it seems for us limited to the Chrome App and one company...but that might just be because we aren't running the Chrome app for any other company.

Another point of interest is that one of my most blocked displays was NOT blocked in our huge issue this morning.  It has not been blocked in nearly a month.  It is running the App and has the same Chrome version as most of the others,  42.0.2311.135

Tony, did you look at using WebM and not MP4s after yesterday's convesation about that?

I have seen blocked screens today as well.  I am also seeing that if I go into Rise Storage, it is acting wonky.  I cannot click on any folder within storage.  It is usually a hyperlink that takes me into the folder.  Now when I click on it, it only checks the box to the left, like you want to download the link or something.

Bryan,

The storage user interface changed early this week. You will now need to double click folders to navigate to them.

OK.  Got it.  It works now.  It worked with one click earlier this morning, so it threw me for a loop.

Not yet.  We'd have a large number of files to convert for all our machines...at least 50 is a guess.  However in this case it seems reasonably logical to say that if 5 machines are running the exact same videos and 3 are blocked sometimes when these blocking epidemics occur, one is blocked sometimes when it happens and one is blocked never, then the videos are most likely not the cause.  Also 3 of the players are only running the URL gadget.

Kaleb & tony,

I am not currently seeing any blocks on your active displays. Can you confirm that these blocks have expired?

tony

  • 11,670 Points 10k badge 2x thumb
They did expire, just like before they hit like a bomb was dropped this morning.  ...and just like before I expect either the problem will magically go way or I'll get hit by an early afternoon wave as well.

Thanks for confirmation. I assure you I'm doing everything I can trying to replicate this locally.

I may have some good info for you here.  It seems sparked by something that happens on the machine that is triggered by the PC clock and not an external clock.  I haven't looked inside the machines (as I said they are all running very visible displays in busy areas)...but I am guessing it's a Windows update or Chrome update or something.  I went through most of the list of machines that were affected and by time the pattern is obvious.  It happened first around 3:30am.  Here is the list of times that I have checked so far.   3:31 3:30 3:36 3:34 3:35 3:51 3:29 3:37 3:35 3:34

On the machine that says 3:51, it made me think because it doesn't fit with the others.  That's when I thought it must be a setting variation.  Sure enough the clock on that machine was about 20 minutes behind.  That means it still happened around when that machine thought it was 3:30 and your system recognized it as 3:51.  That's got update written all over it because the machine is obviously initiating whatever happens.

All,

A quick update. I am still looking into the cause of the blocks, however blocks appear to be dropping off platform-wide. We believe this may have been caused by an anomalous event around 3AM CST, it is limited to users running Chrome App Player, and may have something to do with a update released by Google yesterday.

Can anyone comment on the nature of the blocks? We have a Cenique 410 running on android and experienced a power outage. The TV display is designed to restart when power is reconnected, as should the player. Power resumed and our display was immediately blocked. This just does not seem dependable.

John,

Display blocking is covered at https://help.risevision.com/user/display/unblock-a-display?cid=f114ad26-949d-44b4-87e9-8528afc76ce4

Displays only become blocked when they break a threshold of connections per hour. A few things can cause this, they are covered in the above documentation.

Blake, but what about last night. It sounds like most of us changed nothing and machines that have running without issue and without change were blocked for what seems no apparent reason. ..or not one we could control. I think that was the concern.

tony,

I'm still looking into the cause of these blocks. It's a priority issue for us, and we have another support technician as well as two developers pursuing the cause. When I have a cause, I'll share it. If it turns out to be something within our control, we will take the proper steps to resolve the situation.

It's like there is an update that doesn't play well with Rise once it happens.  So far the only machine that is blocked today is one of the only ones that wasn't yesterday.

We have deployed a change to the nature of display blocking that allows individual displayIDs to contact our servers more often. This should reduce the amount of blocks that we see over the next few hours. If it's not a big enough step, we will continue to make changes until we are satisfied with a solution.
