Help debugging Apache/Certbot failure

I have an Ubuntu 20.04 server running two virtual websites. They worked fine until I used certbot to install SSL certificates from letsencrypt. Now the websites immediately close the connection. It's not giving a certificate error or anything. You can see the results here: [login to view URL] I need someone with experience configuring Apache and Letsencrypt. Should take less than an hour, but I am looking for someone who can solve it quickly and professionally, not necessarily the lowest bid. You should know: - I have completely erased and reinstalled Apache and created new certificates and get the same results. - There are NO errors in the log files. - It's not a firewall issue, i was able to access the websites fine before with a self-signed certificate. You will need to install Teamviewer to access my workstation, then SSH over to the webserver. There is no direct ssh access to the webserver. Do not bid if you're not comfortable with this arrangement. When you are done, I'd like you to tell me what you found wrong so I can correct it if it ever happens again :) Please make sure you mention your experience in your reply. I'm not looking for the cheapest, but I do need it fixed within the next 48 hours. Thank you!
