Microsoft Teams only working on WiFi?

Hi all,

 

we've experienced an issue with deploying MS Teams to staff in that users can only connect to MS Teams when connected to WiFi, and not when plugged into docking stations/networks. When attempting to log in through the network, users are just getting a blank screen. Disconnecting from the network and refreshing the page on the WiFi and staff can log in successfully. Does anyone have any ideas about what is going on?

 

Any help appreciated!

    Check and make sure your not blocking skype services at your network level. Something with your LAN firewall rules for outbound is blocking required services / ports etc. from connecting where your WiFi is less restrictive. Take a look at this article for some ideas. https://mspoweruser.com/microsoft-teams-not-loading-in-many-corporate-networks/
