502 Bad Gateway #2

Closed nickv2002 closed 4 years ago

nickv2002 commented 4 years ago

Hey, I've been using your helper for a few weeks and it was working great. Thanks for sharing it!

Recently however, editing or creating new *.local URLs stopped working and I get the following message when I try to access them:

502 Bad Gateway nginx/1.19.3

My older *.local URLs that I haven't edited recently remain working though.

Here's the tail of the log file from nginx-proxy-avahi-helper (sha256:b73c58fa9edc43df63b934a22889344a204069eb9d449b6aa043fa9c396c1b50, Created | 2020-10-06 02:01:14 )

Any idea what is going on and how I could fix things? Thanks again!

That's going to be a problem with the nginx-plugin not the avahi integration.

It sounds like the mDNS cname has been setup (so this project is working fine) but nginx can't connect to the container.

Thanks for your comments.
