Below are the common errors encountered while accessing to the Plesk
1) Invalid login credentials error
- This error closely related to having input invalid login details while logging to Plesk. Shall you have forgotten the login credentials , feel free to access to Plesk from the client area.
2) "Connection timed out" error which possibly caused by:
a) local IP being blocked by the server
b) Maintenance on the server or service disruption
Solution: May provide the domain name and screenshot of the error encountered to
firstname.lastname@example.org so we could further investigate.
c) Domain is not pointed to the hosting server
Solution: If you cannot access your Plesk using domain-based URLs like https://domain.com:8443/ check if the domain is pointed to the hosting server properly (either using Nameserver records or by A record).
Sample DNS tool : https://intodns.com/
If your domain is registered with a third-party registrar, contact their support and ask to change the nameservers for your domain to the ones specified in your Your Hosting Account Details from the Welcome email.
If your domain is using Domain Registrar’s default nameservers and is pointed to the hosting server via IP address, make sure the IP is the correct one. You can check the IP from Plesk -> IP address in the main section.
d) DNS propagation
When you change nameservers for a domain name, these changes are not accepted instantly all over the world. It may take up to 24 to 72 hours for local ISPs to update their DNS caches so that everyone can see your website.
As such during propagation period, The domain based URLs like https://domain.com:8443/ will not work.
Therefore you can access Plesk via https://serverhostname:8443/ .
