I had a hardware failure on one of my servers, so my webhost provided a replacement on which I ran a fresh install of Hestia (sadly no external backup… lesson learnt).
My first priority is to get mail working again for a couple of the important domains that were on the old server. So I set those up in Hestia, got Cloudflare to point at the new IP and installed the LetsEnrypt certificates.
I can connect to webmail and the mailboxes work. If I try and connect from Apple Mail it’s “Unable to verify account name or password”. If I use the MS Remote Connectivity tool, it tells me it can resolve the host name, but that port 993 is blocked. In Cloudflare I have the mail subdomain set to DNS only, so that should mean Cloudflare isn’t blocking it, right…?
Additionally, if I try to access the Hestia CP via its domain name and port 8083, I get a security error saying HSTS is enabled but no valid certificate. If I just access the domain name via port 80, It’s a secure connection. I can only access the Hestia CP via an IP address.
Any of this sound familiar?
