My discourse upgrade failed just like on these posts
- Upgrading cannot allocate memory
- Docker Discourse multisite 502 bad gateway, after bootstrapping both app and data container
but I am still lost at 502 Bad Gateway.
After the upgrade failed, I read that I should restart the app. Unfortunately and stupidly I reboot the server then 502 bad gateway happened
How I can fix this? at least get me back to the site and maybe postpone the upgrade
yes, I am aware that my discourse installation is under the required memory spec
