A client has requested to whitelist a website. However, this site is already categorized as Allowed.
During a call with the client, it turns out that the site is indeed reachable, yet as they try to login, they weren't able to.
Thus, I assume, some other links and domains must be allowed as well.
I'm trying to troubleshoot, how can I know for sure what are the links that should be authorized for this website to work correctly?
Thanks in advance.
