An integration will not connect

1. The account you authorised with

A connection inherits the permissions of the account that authorised it. If that account cannot see the data in the source system, neither can we. Authorise with an account that has the access you need, and prefer one that belongs to the team rather than to a person.

2. Network rules

Some systems only accept traffic from known addresses. If yours does, add our published addresses to its allow list.

3. The scope you were asked to grant

If the authorisation screen listed fewer permissions than expected, the app registration in the source system is limited. That has to be widened there before it can be granted here.

If all three check out, contact support with the time of the failed attempt so the request can be found in the logs.
