Self signed certificate for SIM

[User2804]

I'm testing the SIM integration and having a problem getting the post back from Authorize.net ( RelayResponse).

The site is hosted on public server ( Azure cloud) and port 443, 80, 88 are allowed for inbound and outbound traffic. The only thing I can think of is that I used "Self Signed Certificate". I was wondering Authorize.net postback to website which uses self signed certificate?

The error I get is 

"

Your script timed out while we were trying to post transaction results to it.

   Transaction ID: 2180986720

Transaction Result: This transaction has been approved."

Postback link does not need any authentication. 

Any help is much appreciated..

it will probaly get a 403 when try to relay the response and the result is the error you are getting.
