My server has an IspCONFIG with Apache on Ubuntu 20.04. Also i issued 2 single-domain PositiveSSL via Namecheap for config.example.com and example.com. Domain is managed by Namecheap ISPCONFIG provides self-signed ssl for control panel (config.example.com). I don’t really sure what is issue, but when i install PositiveSSL on main domain (example.com) it says that it is untrusted, and when i install other SSL on config.example.com it says that it is issued for example.com, however i issued it for config subdomain Comodo support is “unbelieavable”, so i can’t reach to them.
