Hi everyone after migrating to new servers using a new ISPconfig version, I have a problem for newly created websites: they display an error message about the website not being secure (which is OK, since the browser is redericting to https, because it has been accessed before using SSL), but a wrong Let's Encrypt certificate is being displayed. It's the certificate of an existing website from our server, but it's a "random" one (the first one alphabetically, I guess). Once I enable SSL and Let's Encrypt, everything works fine. Is this a known error? If so, how to solve that?
