AAD Connect Endpoint Error

Frequent Contributor

This is now the second time we are getting this error.  The Fix Azure Support recommended was to build a new server, so we did.  Now 5 months later were right back here again.  I am lost as to WTH is going on.  Our Sync is broken and I am at my wits end here,  Im hoping someone out there has some info on how to fix this without me having to build a new server.  I upgraded from 1.5.30 to 1.5.45 in hopes that it would fix this but no go.  Im lost and I really need some help.  Here is the error:

I ran a test to that URI from Posh which I found online and that seems to work so I dont get why the sync server is having an issue with that End point  Here is the output.

Ive been seeing the same issue across all out Domain controllers and AAD connect servers running Azure AD connect health. Did you ever get to the bottom of this?

Nope, if I run the AADCONNECT PS Script that checks all the endpoints it still errors out.
It has been working or i should say it has been sending over local AD changes to Azure.
However these errors that caused it to crash have stopped. I cannot say what the issue is cause MS is clueless. They themselves saw the errors to specific endpoints and did not know how to resolve. Im basically living on borrowed time cause sooner or later I think its going to break again. I ran the script 3days ago just to see if the errors still occurred and they do.

Thanks Christian,

 

I actually got to the bottom of our issues. It was caused by outbound IPS monitoring on our Fortinet firewalls. We have a cause open with them investigating it but for now at least we have a workaround.

 

Regards
