what do I have to do to get my mailbox working 1. create dns 2. create new website (check make sure it is working) 3. create new email domain 4. create new mailbox 5. when I click the link behind mailbox it redirects me to my servername server1.computer-hosting.com i can't access computer-hosting.com:8080 I get computer-hosting.com normally uses encryption to protect your information. When Avast Secure Browser tried to connect to computer-hosting.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be computer-hosting.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Avast Secure Browser stopped the connection before any data was exchanged. i can only access ispconfig with ip i created a website for computer-hosting.com You cannot visit computer-hosting.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.
your actual server is using server1.computer-hosting.com, which doesn't have any A records in the dns, and the ispconfig gui is running on a self-signed certificate. create an A record for server1 in your dns. run ispconfig_update.sh --force and let it create a new certificate for the interface. and if you want to access the gui using just computer-hosting.com, you'll need to either add that as a server alias to the ispconfig vhost, and the letscencrypt/acme.sh cert request, or create is as a standard website in ispconfig and configure the apache/nginx directives to reverse-proxy it to https://server1.computer-hosting.com:8080, and then you would just access it using https://computer-hosting.com, not via port 8080.
