mscmgr.log - Display: Call to HttpSendRequestSync failed for port 80 with status code 500

Hi guys,

This is my first topic and I hope have a solution for this problem in my SCCM 2012.

In my mscmgr.log - Display: Call to HttpSendRequestSync failed for port 80 with status code 500, how to fix this?

My troubleshooting were:

1. http://sccmservername/sms_mp/.sms_aut?mplist; - OK - display my MP FQDN
2. http://cl-hyv-cm01/sms_mp/.sms_aut?MPCert; OK - display some letters and numbers
3. http://cl-hyv-cm01/sms_mp/.sms_aut?mplist1; OK - display my MP FQDN
4. Reinstall my MP and mpsetup.log is OK display my MP installed with sucess;
5. I have check another settings and reinstall my IIS;

Any idea? Thanks.
