SCCM2403- Site Server MP is showing Critical. error is Call to HttpSendRequestSync failed for port 80 with status code 500, text: Internal Server Error Http test request failed, status code is 500, 'Internal Server Error'.

1 SCCM CAS SERVER with SQL DB

1 SCCM Primary Server and 1 SCCM Site Server-- (SQL DB with High AV.)

Site Server MP is frequently going Critical .

error message in log is :

Call to HttpSendRequestSync failed for port 80 with status code 500, text: Internal Server Error
