502 bad gateway error

While I was overseas with no access to my Google compute instance (Great Firewall) I was advised of this error.

Maybe I had too many backups that were accumulating while I was away. But I followed the advice on previous reports but now although the 502 error has gone, I’m now getting no response.

So, I did a rebuild, cleanup and autoremove.

What information do I need to provide to help fix this?

I’m not quite sure what are you trying to fix here?

Too many backups? Considered using a storage provider to store backups? E.g. AWS S3/DO Spaces/Minio ??

I don’t get any errors on starting the docker instance using ./launcher start app but the webserver is no longer responding other than redirecting to https

$ wget 19:27:11-- [] (https://ssh.cloud.google.com/devshell/proxy?authuser=0&devshellProxyPath=%2F&port=null)Connecting to connected.HTTP request sent, awaiting response... 301 Moved PermanentlyLocation: https://forum.rebol.info/ [following]--2018-08-28 19:27:11-- https://forum.rebol.info/Resolving forum.rebol.info (forum.rebol.info)... to forum.rebol.info (forum.rebol.info)||:443....

PS: If I use quoted text for the above, meta.discourse.org responds with a server error

This post says that there should be a redis log at /var/discourse/shared/standalone/log/var-log/redis but I’m not seeing the redis directory. The unicorn.stderr.log seems to be saying that it can’t connect to redis.

I installed redis-cli, but even on redis-cli ping I get a connection refused

$ redis-cli ping
Could not connect to Redis at Connection refused

Where can I find the redis log? it’s not where it’s supposed to be viz: /var/discourse/shared/standalone/log/var-log/redis
