I am hitting into a new issue that I haven’t encountered over years of working with CyberPanel. When I added an SSL (one from another company not generated using letsencrypt) the SSL took effect for the domain I added it too but it now validates for all other domains the server is hosting. Something has went horribly wrong and I don’t know enough about the scripts that do the ssl work to understand what happened. Also, going to /etc/letsencrypt/live/ and editing the cert/fullchain/privkey in the domains located there does nothing.
Welcome @ProCreator Happy you are here
