Server is still running, services, dockers, shares are working, except unraid web gui.

I get
500 Internal Server Error in browser
and

Feb 28 11:44:53 Tower nginx: 2020/02/28 11:44:53 [error] 25390#25390: *10600536 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.0.115, server: , request: "POST /webGui/include/DashUpdate.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock", host: "tower:8888", referrer: "http://tower:8888/Dashboard"

Have you done memtest?

 

Go to Tools - Diagnostics and attach the complete Diagnostics zip file to your NEXT post.

@trurl I'm trying to learn how to read these logs better, what line should be telling me to think memtest here?

GPF is a clue but not definitive

Memtest clean

Diagnostics attach
