SOLVED No response from subprocess (securitypolicy):

[kemraj]

I'm on a dedicated server and sine the automatic edge of cpanel i'm getting this error after login in to WHM(only after)

Internal Server Error
500

No response from subprocess (securitypolicy): The subprocess reported error number 255 when it ended.
cpsrvd/11.61.9999.66 Server at server

I tried
/scripts/upcp --force
Then restart Cpanel

Still noting.

Check the error logs and see this.

Undefined subroutine &Cpanel::SecurityPolicy::UI::html_http_headers called at /usr/local/cpanel/Cpanel/SecurityPolicy/UI.pm line 48.
[2016-11-18 02:23:14 -0400] info [whostmgrd] Internal Server Error: "GET /cpsess2877982634/?login=1&post_login=59024258991388 HTTP/1.1" 500 No response from subprocess (securitypolicy): The subprocess reported error number 255 when it ended.

Can someone please help.

Hello @kemraj,

Internal case CPANEL-9750 will address this issue in the next EDGE build. You can monitor the Change Log at:

62 Change Log - Change Logs - cPanel Documentation

As a temporary workaround, you can disable two-factor authentication via the command line through WHM API 1:

whmapi1 twofactorauth_disable_policy

The function is documented at:

WHM API 1 Functions - twofactorauth_disable_policy

Thank you.
