This site can’t provide a secure connection

Not sure what happened. Maybe after a reboot. But I cannot connect to admin. It does come up if I use http instead of https. Can anyone help?

Issue hostname SSL for it 2 - CyberPanel on SSL - CyberPanel

why was it working before ? I was using my ip address to access the panel.

what does it say if you

curl -I -XGET -k https://your_ip:8090

HTTP/1.1 200 OK
Vary: Accept-Language, Cookie
X-Frame-Options: SAMEORIGIN
Content-Type: text/html; charset=utf-8
Content-Language: en
Content-Length: 7352

if you can curl it , means :8090 is working fine , maybe a firewall?
