I am having issues on one of my cPanel servers when trying to login to WHM/cPanel using the WHMCS integeration that uses API keys.

The error I am seeing is:

An Error Occurred
cPanel API Response: Internal Error (ID 294982937238277)

I checked cPanel error_log file for the corresponding error ID and this is what I found

[2022-02-28 23:28:29 +0000] warn [whostmgrd] The subprocess (whostmgr (xml-api)) exited with an error (ID 294982937238277): at /usr/local/cpanel/Cpanel/Server/Handlers/SubProcess.pm line 263.

I tried updating cPanel, rebooting the server, double checked the API key I was using was correct and the permissions were set right, also created a new API key but none of them worked.
I checked WHMCS module logs too and I could find the same error being logged there.

The server was installed just yesterday.
