My organization is hosting several instances of AGOL, and in some cases users are using their logins to authorized their software. We have some users on a difference network domain who are able to authorize without any issues, while users on the other domain are not. Both users are able to access the AGOL sites without issues. What were currently thinking is this could be result of a port being blocked.
Where could I find information on which ports need to be opened to authorize software?
