Direct Admin URL with 2222 no SSL - ERR_SSL_PROTOCOL_ERROR

[RO3B]

wildcard ssl not covering with hostname that use to access Directadmin Panel.

You must issued seperator.

/usr/local/directadmin/scripts/letsencrypt.sh request_single your.hostname.com 4096

That's what i already did and i already have server. ssl but the mail.example.com i'm having problem with connecting to 993 and 578 or 995 & 25

Did you check the crt.sh site I mentioned?

For anybody else suffering from "ERR_SSL_PROTOCOL_ERROR" or "record too long" on Firefox when visiting DirectAdmin, and if you have Imunify running on your server, it is a possibility it has greylisted the IP, which causes captchas, and as Imunify was not able to show the captcha on 2222, it displays this SSL error.

Check the IPv4 via: https://checkip.amazonaws.com or IPv6 via: https://ip.me
Just whitelist the IP or remove it from the greylist on Imunify.

CLI Command for whitelisting:
imunify360-agent whitelist ip add <ip>
