Error after upgrade - "MP Control Manager detected management point is not responding to HTTP requests"

[mikedisd]

I've just upgraded from 1511 to 1610 and now I am getting the following error under Site Status / Management Point (and mpcontrol.log):

MP Control Manager detected management point is not responding to HTTP requests.  The HTTP status code and text is 500, Internal Server Error.

I've checked / attempted the following:

• {EDIT} Made sure the the SQL database instance has the CM computer account set as *italics*sysadmin*italics*.
• The Windows firewall is off.
• Installed all Important and Recommended Updates / rebooted.
• Uninstalled the MP role, restarted and reinstalled the role.  Mpsetup.log states the install was successful.
• Validated the CM service account (pwd's correct).
• Ran iisreset after most steps.
• Checked the CM server still has full access to the Systems Management OU in AD.
• Set "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM\CcmEval\NotifyOnly" to TRUE, uninstalled the MP role, restarted, reinstalled MP role, restarted.
• Tried the trick outlined here:  https://www.anoopcnair.com/configmgr-sccm-2007-mpcontrol-log-shows-httpsendrequestsync-fails-with-status-code-500-internal-server-error/

We have a simple setup of 1x primary CM server and 1x SQL Server, both running on Server 2012 R2.  Running out of ideas except to rebuild CCM.  Any suggestions?
Thanks.

[EDIT]: Further steps tried:

• Performed 2x system resets through the builtin ConfigMgr Setup Wizard as mentioned here: http://vworld.nl/?p=2228
• Installed .NET 4.6.1 as replacement of 4.5.2.
• Removed and added the default webpage binding of port 80 to *.

What CM services account at you talking? CM uses the computer account for just about everything.  Does the CM site server computer account have full admin and SA rights to SQL?

My mistake, the CM computer account has sysadmin rights to the SQL server, db_owner of the CM database and local admin to OS.

Gave up, restored from backup, now back at 1511....

BTW, after re-reading the above, It is unclear to me if you uninstall IIS and rebooted. then Re-installed IIS.
