Can't reach web UI (upstream timed out)

[Tibbe]

My Unraid server's web UI has become unresponsive. I can still SSH to the machine and a restart has no effect. /var/log/syslog has lots of these:

 

Jan 24 17:42:09 Tower nginx: 2022/01/24 17:42:09 [error] 10604#10604: *6414381 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.5.64, server: , request: "GET /login HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock", host: "192.168.5.100:9080", referrer: "http://192.168.5.100:9080/login"

 

Trying manually with curl has the same effect (i.e. curl just hangs waiting for the HTTP server response that never comes.)

From a command prompt, can you 

diagnostics

and upload the resulting file here.

[Tibbe]

Unfortunately "Starting diagnostics collection..." never finishes (that's why I uploaded some files manually above). I suspect that perhaps it's trying to make HTTP requests to the server and therefore hangs, just like my web UI connection.

Yeah, the diagnostics doesn't make any http connections.  Your best bet at this point then is to restart in safemode via the boot menu and then post the diagnostics.  If you still can't get anywhere, then in /config/disk.cfg on the flash drive change startArray="yes" to be startArray="no" and reboot

[Tibbe]

I will try safemode. There seems to be no /config/disk.cfg? Is it in some other subdirectory?

 

Update: fixed typo. There's no /config/disk.cfg

7 minutes ago, Squid said:

/config/disk.cfg

on the flash drive.  So if you're doing this via the command line in the terminal the path is /boot/config/disk.cfg

[Tibbe]

I had a typo in my above post (but not in my actual command). /config doesn't seem to exist:

 

# ls /config
/bin/ls: cannot access '/config': No such file or directory

From the command line it would be /boot/config

I don't know what the problem in the end but switching to a new USB drive and transferring my key there worked.
