Can't open website

I installed discourse on a VPS two months ago, and everything have been working fine, until today…

When I visit my website today, nothing can be loaded

“Oops.

The site at https://forum.xxxx.org/ has experienced a network protocol violation that cannot be repaired.”

I remember I visited my website two days ago, and everything was fine by then. Since then, I remember I did some Ubuntu upgrades, and didn’t upgrade anything related to discourse.

I’m the only user of the forum.

here are the outputs of the nginx log:

The site redirects elsewhere. Perhaps it’s a dns problem? did the domain expire?

That traffic all looks like script kiddie stuff.

A common problem is a full disk, but maybe your certificate expired?

The rails production log would be more helpful.

It’s the certificate problem, the certbot didn’t auto renew. Thx a lot. :rofl:
