Hi there, I use one server for the newest version of ISPConfig on Ubuntu 18.04, Apache and MySQL. I have four domains running on my server. I need SSL encryption on two of these four domains. Therefore I activated SSL and Letsencrypt, created the certificates and now only one of the websites is shown on both domains. [first domain].com -> shows the correct content [second domain].com -> shows the content of first domain I have already tried to debug this and tried the following: creating a site with 000 in the front, in order to stop the wrong content from being shown (third domain works, fourth domain shows third's content) enable SSL forall four domains and have SSL certificates generated Both things have changed nothing. I also looked on my Webmin panel and only for the two domains, which shows up correctly, there is a webserver listening on port 443. The other two only show up on port 80. I get, that "this is the way that webservers work", however I am somewhat new to this and after 4 hours of trying to resolve the issue myself, I feel like I should probably ask for help. Thank you in advance for helping me! If you need any further explanation, I am happy to provide it.
