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.)
