Terminal tool - Error: The WebSocket handshake failed

[G-e-o-r-g-e]

Hello - hope you're well.

I'm trying to access the Terminal tool inside cPanel.

I get this error:

Error: The WebSocket handshake failed at 9:47:43 AM.

I'm not using a VPN.

I have tried with both Firefox and Chrome.

Rebooting my PC didn't help.

I have tried to login from both of these URLs:

https://domain.tld:2083/

https://domain.tld/cpanel

I have used the terminal in the past with no issues.

Can this be fixed?

Thanks!

If neither of these articles applies, I recommend creating a support ticket with our Technical Support team so they can take a closer look at the issue. Please post the ticket number here if you choose to do so I can follow along and make sure the thread stays updated.

It looks like our team found a conflict with Enginetron that could be partially to blame for this behavior.
