Firewall rules required for powerBI server authentication

[Igoris]

Hello all, 

Can someone help to configure the wirewall to be able to isolate powerBI server? 

We have a problem of not being able to go past the authentication to MS as we are not sure what rules to use to allow it through FW. We have allowed most of urls according to the documentation online but the issue still persists. Perhaps someone could help to summarise what to whitelist? 

thanks
