IcicleTrepan Posted August 21, 2021 Share Posted August 21, 2021 A couple of days ago my web gui simply stopped loading. The server has been rock solid for years and I am not exactly sure what happened as I wasn't doing anything with it at the time. All of the dockers were still up and I can access the command line, I just couldn't access the web gui. I get the following error in Chrome but it doesn't work in any other web browser either: This site can’t be reached The webpage might be temporarily down or it may have moved permanently to a new web address. ERR_HTTP2_PROTOCOL_ERROR So I tried rebooting the machine and the dockers etc all came back but the web gui is still MIA. attached is my diagnostic log. Thanks in advance! asgard-diagnostics-20210821-0002.zip Quote Link to comment
trurl Posted August 21, 2021 Share Posted August 21, 2021 Network problem. Check ports, plugs, cables on server, switch, router. Quote Link to comment
IcicleTrepan Posted August 21, 2021 Author Share Posted August 21, 2021 I checked the cables, they seem fine. Some additional information. I've tried rebooting the server and the router with no change. I'm able to watch movies on Plex, even outside of my network and I can access all of my docker containers' web guis just not the one for unraid. Additionally, I can ping both NIC IP addresses and get replies, so the server appears to be there. I'm not really sure why I can access everything else but just not the unraid web gui. I also have mapped network drives on the same server and I can access those no problem. Quote Link to comment

Can you access the webgui at: https://<ipaddress> (note: https not http) (you will need to acknowledge a certificate error in your browser) If that works, then go to Settings -> Management Access and set "Use SSL/TLS" to No. That should allow you to access the webgui at http://<ipaddress> (note: http not https) Quote Link to comment

ljm42 Posted August 21, 2021 Share Posted August 21, 2021 So https://<ipaddress> gives the generic 'ERR_HTTP2_PROTOCOL_ERROR' with no way to get past it? Bummer. To disable SSL in 6.9.2, you'll need to modify this file on your flash drive: config/ident.cfg and change: USE_SSL="yes" to USE_SSL="no" and reboot. Quote Link to comment

That has done the trick. so it seems like SSL was the issue, but how do I fix it? Quote Link to comment

On the flash drive, delete any files in this directory: config/ssl/certs then you can setup SSL again. The exact procedure depends if you want to use a self-signed cert, your own cert, or Unraid's Let's Encrypt cert. I'd recommend going to Settings -> Management Access and turning on the help.
