I’m working on a WordPress site for a client that involves importing a whole bunch of their legacy content. I decided to work with a copy of their old database for this. I set it up locally in Sequel Pro, accessed
/wp-admin, and was met (as expected) with a “You must upgrade this database”-style screen. I clicked the button and… nothing. Eventually I had a 504 error.
I use Laravel Valet to develop PHP sites locally on my MacBook Pro, so I checked the NGINX error log
~/.config/valet/Log/nginx-error.log for hints about what was going on. I repeatedly saw an error along these lines (highlighted bits are altered by me to be more generic):
YYYY/MM/DD HH:SS:MM [error] 52486#0: *14 upstream timed out (60: Operation timed out) while reading response header from upstream, client: 127.0.0.1, server: , request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://unix:/Users/username/.config/valet/valet.sock", host: "hostname"
I searched online and found a bunch of suggestions, about checking the
valet.sock file, about increasing the
fastcgi settings in the NGINX config, etc. Nothing seemed to work.
I then came across this issue which sounds super similar, and they seemed to resolve it with a reboot.
Worked for me too. Turn it off and on to the rescue again. Wanted to mention it here in case anyone else is banging their head against the wall at some point.
