Server Disconnected Code 1006

[HStep20]

OS: Unraid

I've been having issues with this for the last couple months. Even through updates, I haven't been able to connect for some time now. When I initially went troubleshooting, I thought it could be a problem with another application using vnc at the time, but I shut down all my other containers, and still had the issue connecting. Settings are all set to default.

I did notice this error in the logs, but everything else looks to be running as expected in them:

25/08/2021 18:36:55 rfbProcessClientProtocolVersion: read: Input/output error

Not sure what other info is helpful, but Im happy to help with whatever info you need.

Hi @HStep20, can you please post the full logs for the container? Thanks.

[HStep20]

Here are the logs from the container: https://pastebin.com/dfZEm7z9

[mikenye]

Thanks. Those log messages look normal. Are you able to share the container configuration?

[HStep20]

The Width/Height were default before, and it still had issues. I just changed them an hour or so ago when I started troubleshooting again.

[mikenye]

Can you start the container, and then run the CLI command docker ps -a and post the output here?

[HStep20]

Heres is the line its grepped from:

[mikenye]

OK, so when you browse to http://ip.of.unraid:5800/, what shows in your browser?

[HStep20]

Just an empty window with the vnc controls

[mikenye]

Any additional information in the logs?

[HStep20]

Nope. That log was everything in the unraid logs.

Are there internal logs saved in the appdata I could pull?

[HStep20]

Interestingly, it works in different browsers, but not firefox. I expect its due to a privacy plugin I have, but its odd that other vnc apps work with the same plugins enabled.

[mikenye]

Can you post the output of docker inspect MusicBrainz-picard? If you've set a VNC password or have any other sensitive information in there, please sanitize before posting publically.

[mikenye]

Oh, that's interesting... Are you able to whitelist?

[HStep20]

Likely yes, I just need to figure out which one of the many plugins is doing it. I can update this comment when I get a chance to work that out, but unless you want to pursue solutions to things like that more, you can probably close the issue. Thanks for the help

[mikenye]

I'll close out the issue :)

Thanks.

I'm experiencing this with Firefox on a "clean" install of Firefox - no extensions. Works in Chrome, even with adblockers. There may be an incompatibility with Firefox in general.

[timgilbert]

I'm seeing the same behavior here, also on unraid and using Firefox 101.0 to connect (from a linux desktop, FWIW). I get the same rfbProcessClientProtocolVersion error message in the logs and the same GUI screen with an "unable to connect" message. Using Chrome 102.0.5005.61 from the same desktop seems to work fine.

[HStep20]

So, I do want to point out that this is more likely a firefox issues than it is a container issue. I see this same problem on all of my containers that open with the vnc image that you use here. Opening them in incognito mode in firefox works perfectly fine (for me at least), and this is the same behavior with any vnc built container. Custom containers Ive built with it, cloudberry backup, the Ravencoin Wallet container, and all others with this baseimage seem to have issues on firefox.

[ohare93]

Same issue here. Works in a Firefox private window. Very strange.

[Strider11]

Brave gives the same result as Firefox. Doesn't work in a normal window, but private window works just fine.
