Hi there. This problem has happened to me on previous occasions and I have been able to access the cPanel via the URL:
https://x11.x10hosting.com:2222/
Luck!
Hi. I cannot access cPanel. The login is correct, but when trying to 'Open cPanel' it responds:
Sign in Successful
Please standby while transfer you to your web hosting account.
An error has occurred forwarding your sign in. Retry
... and so on indefinitely...
Thanks!
