We have a application that is struggling to connect successfully to cloud services for DNS verifications etc. Our TMG server is denying connections when logging is enabled from my local computer.
I created an access rule allowing all outbound traffic from internal to the specified range. When i launch the app from my pc, i do see successful connections however vast majority are logging the following:
I noticed that there does not seem to be a rule applicable resulting in the denied connections? Is there any other rule that i need to create to ensure successful connections?
