Hi @SM !!!
~
My problem is similar, there is something that is no longer working properly with the Hostanme SSL.
~
1.- Delete SSL hostname in Module SSL Certificate
2.- Re-Generate HOSTNAME - Module Change Hostname
3.- Genrerate new SSL for hostname in Module SSL Certificate
4.- Again Re-Generate HOSTNAME - Module Change Hostname
5.- In my case, Apache stops, and with it, all my sites too, but after performing these steps, I just need to restart it.

This is very cumbersome and annoying, but it's the only solution I've found, so I hope it helps someone else.
