Not sure how to correct this. ISPconfig 3.2. Going to the admin interface it is using a let's encrypt certificate. https://host.domain.com:8080 is secured with a proper certificate. However I had an issue where mail users were getting an invalid certificate warning. A suggestion on this forum was to add host.domain.com as a site in the sites tab with LE turned on. So i've had that for a while. if you visit https://host.domain.com you get an invalid certificate warning. So the admin panel is using the cert but visiting the server without :8080 you get a warning. Inspecting the certificate i can see it's a self signed cert from when I installed the server. All other sites on the server have a correct LE cert applied to them. The issue is the host and it's certs. What is the proper way to fix this so the admin panel and mail users are presented with a valid let's encrypt certificate? Should I delete the site i added for it, is that causing a problem?
