No Access

We have opened up the firewall ports and requirements for Intune Connector Network requirements, I can login to https://endpoint.microsoft.com and I can get to the MEM admin center. But, when I click on any of the options for ex devices and windows enrollment, I cannot see any other options. 

It says no access as shown. This is for all the options in MEM admin center. I am working with the Network Engineer, but want to know what else should be opened up on the firewall side in order to get access to the full MEM admin center and its options.
