I just had to reinstall Jitsi on Ubuntu Server 20.04.
With previous installation I had not problems at all but, this time, no way to generate the Lets Encrypt certificate.
As described in the Self Hosting Guide - Debian/Ubuntu server I’m attempting to generate a Lets Encrypt certificate by running script sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh.
Well, I’m returned the following:
Timeout during connect (likely firewall problem)
To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you’re using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
No ideas what to do considering that everything is the same as before, DNS record included.
