I wonder if anyone else has experienced this problem or has any ideas what could be the cause.

This has been an issue with my Unraid server since I first built it and I thought maybe it could be related to the fact it was a pretty old base, an i7-2600k based system. However, I rebuilt the system last night with a MAG-Z690 Tomahawk and i3-10100 last night and it's now doing the same thing this morning - it was all fine last night.

 

The basic problem is that randomly, the processor, system ram, interface, etc go blank. The array and cache will correctly list size and usage, but will not list any devices. Clicking on Main will not list any devices either. Also, any attempt to launch a terminal window for the main unraid system or any docker will pop up and then close down again. This happens randomly and goes away on its own. Sometimes a reboot SEEMS to fix it, but not every time.

 

Everything functions correctly, sharing still works, all the dockers still run.

 

I just noticed that with the stats plugin, the system stats are updating live.

 

Any ideas what could be the cause?

 

So it's not the first time I've tried to troubleshoot this problem, but it looks like I've figured a few things out properly for once. I just noticed that if I launched a NOVNC connection to my Home Assistant VM, it would suddenly kick in to life - then clicking on the Main tab would be blank and would stop the data being captured again.

 

For the first time I could consistently stop and start this issue of data not being captured - great.

 

Further investigation has revealed that it only seems to be an issue if I access the GUI via IP address, the way I've always used it. I had it setup with a custom local TLD in the past, but as a test I just tried it with .local - and it displayed all the data - I also tried the myunraid.net URL and it worked okay with that. So for some reason - intermittently, it doesn't like the use of local IP addresses - I suspect the browser is rejecting it without issuing the 'Are you sure you want to access this data' prompt.

I'm having the same issue here for the first time. I have a VM that crashed as well so I initially thought this was related

 

I meant to post, I've been doing more troubleshooting - it seemed to be down to the stream of data from the server being blocked - I re-loaded the browser and it worked again.

 

For some reason, browsers now seem to time out on unsecure pages even when in use, so this seems to be the root cause.

Has anyone found a clearer answer to this problem? I've been struggling with the same things for days. I see the same broken interface on whatever browser or device i am using, and on both local IPs, unraid.net or tailscale addresses. Thanks in advance.

Try using a different browser, or even a different device, like a phone or tablet.

This issue is quite a nuisance, I never found a solution. Using another browser works - until it also encounters the same problem after a little while.

 

The only 'fix' seems to be to close the website in your browser and wait a fair while - very frustrating.

 

It doesn't just affect the data from the display on pages, you also can't open any console sessions from the web, or the logs as they are all blocked.

What version of Unraid?  Also what page is the GUI sitting on for (presumably) an extended period of time?

It's happened with all versions, I'm on the latest update now. It doesn't seem to be tied to any paraticular page on the GUI, just an overall function of having been logged in for a while.

 

It seems to have begun when the browsers got stricter about what they consider secure.

I haven't done any testing recently but I recall that if I was accessing via a hostname rather than an IP, with a suitable SSL it would never give this problem.

Randomly started happening at me as well.
Some browsers are fine (for now) and some just have this issue constantly.
Tried to reverse proxy it with an certificate attached, however there is no improvement.

Browsers it does show the issues for me: Vivaldi
Browsers it does not show the issues for me: Firefox

Though I must say that surely something can be changed to counteract this. I assume that if it was some general to browsers, surely other software would have issues as well.

Funnily enough, half the browsers have it working when I use the IP instead of URL but others have it the other way around.

It might help if you can set your browser not to ‘sleep’ any tabs that are open to Unraid.

Sadly not.. depending on the browser direct IP or URL works (and not the other option so its a 50/50 on what works or not :D) and doesnt matter how long the NAS has been running, how long the browser (or any browser tab on any device) has been open.
For example right now going to the directIP has the Main tab filled, but when using reverse proxy its empty. However before or if I change to a different browser now, the direct IP has this missing while with reverse proxy it does work.
It just seems to randomly decide when to start acting up even (Never had a single issue for the past month and now its suddenly doing this)

There is something in Unraid having an UI issue here, but its very hard to pinpoint as a user to say the least .. doesnt seem much logic behind it :D

I created a user script to restart interface withtout restart system

 

#!/bin/bash

/etc/rc.d/rc.nginx restart
/etc/rc.d/rc.nginx reload

 

And works for me
