Matrix homeserver not working

I can no longer write any messages from my account registered on the home server. The web application login screen loads fine, but has the following text:

Your NitroChat is misconfigured
Ask your NitroChat admin to check your config for incorrect or duplicate entries.

According to the text, this is a server-side issue, not client-side returns 502 Bad Gateway

So when will this be fixed? By the way, the server has been down since this morning

It’s working now again.
