Update: On about the tenth try, I was able to rebuild.
I don’t know if it had any effect, but I did update the docker engine to the latest version.
However, although the container is running, I am unable to access the page. It keeps telling me that the server IP address is unavailable.
I have also tried to access the site from another network on another device but to no avail.
As I mentioned, on the same VPS, I am running WordPress on the main domain, and everything is working fine. I don’t understand how Discord could stop working so suddenly.
Any ideas? I’m getting really desperate.
