SOS! My virtual servers suddenly stopped. I can’t access any of them, for example https://demo.oclockdt.com.
I rebooted. but it’s still the same.
It all started when on one of them the SSL stopped working without warning., I did:
sudo certbot certonly -d ce.oclockdt.com
and everything stopped working. Can you help me? Thanks, The whole system is down!
I just want to mention, you should only use certbot directly if Virtualmin is not managing your Let’s Encrypt certificates. (It’s fine, either way, but, there are differences in how things work and where files end up, and if you try to use both, you’ll confuse yourself and both tools.)
