nginx 502

pieter coussement

hi,

In installed galaxy locally on debian. I'm using nginx as webserver.

However now and then I get a 502 bad gateway. refreshen fix it immediatly, but it doesn't really make it practically...

This is the nginx.conf file I'm now using.

Any help, tips, or suggestions are really welcome!


best regards,

pieter
