WHM / cPanel not load - ERR_CONNECTION_TIMED_OUT or 500

Good day,

yesterday I logged into my WHM account and all the pages load too long time or an error popped up (internal server error 500). In the upper right corner, I saw the option to restart the server to download the software update. I thought it would be the cause of the problem and that nothing could go wrong. I ran "Graceful Server Reboot" and now I cant log in to my account at all. This is an ERR_CONNECTION_TIMED_OUT error

The website worked properly but the reboot turned it off, the domain also lost the https certificate.

As for the server, I have my own dedicated. Its condition was verified with the provider's technical staff. Server utilization is not even 1%.

As for IP addresses, DNS ping over CMD is fine but IP / domain ping is unresponsive.

Where is problem? What should I do with it? Please advise anything. I'll pass the information on to my technician when it's online, thank you.

If you get error ERR_CONNECTION_TIMED_OUT and the provider's technical staff says the server is ok I would suspect that your IP is blocked by the server firewall.
You could try to connect using VPN (Opera browser has built-in VPN).
