Iredmail problem connecting from outside?

Question

linux

Good evening.
The other day I decided to set up iredmail on an external IP with a domain, with blackjack and these same ones. I collected all the rules on Mikrotik, from the inside everything works for 5+, even mail comes and goes, but the problem from the outside via https does not get on the web face. On Mikrotik, against the rule (443), it costs 0 and that's it, but the rest of the rules work, and the mail goes.
I don’t know where to dig, I got such an error ERR_SSL_PROTOCOL_ERROR, yes, I know that the matter is in the certificate, but for now, tests and all that, how can I get around it?
Thanks to everyone who responded

You can try to fasten the graphical environment, and cling to VNC, for example, and then twist it as you like.
