ATT issue connecting to Microsoft Teams and LinkedIn
Hi,
There is an issue with our AT&T connection. We cannot connect to certain sites such as Microsoft Teams and LinkedIn.
Other sites work just fine, but not those two. We tried connecting via a different WiFi away from home, and the sites loaded. They will not load at our home though.

What is the behavior when they will not load? What error message(s)?
Have you tried using PING or TRACERT to see what the network path to the server looks like?

It would be interesting to see what the following command (executed in a CMD window) would show:

Well, both Teams and LinkedIn are products of Microsoft, and they are both, unsurprisingly, hosted using Azure resources. The IP given for www.linkedin.com reverses with a generic edge server for Azure: l-0005.l-msedge.net.
The traceroute seems to work... is that the same device and connection on which you're getting the timed out messages?

Yes it is the same device. Also, the links will not work on any of our other devices, which all use AT&T.
Thanks for your assistance. This is much appreciated.

The traceroute seems to show that AT&T is properly delivering the packets to the Microsoft/Azure network, so there's little else to add to the conversation regarding AT&T.
It may be that Azure is blocking access from your AT&T-assigned Dynamic Public IP address either on purpose or accidently. I will likely be extremely difficult to get to anyone within Microsoft network engineering to even listen to your issue, so I don't really know how to tell you to proceed. If you're using Teams with a business, perhaps your business can engage MS support to look into your issue.
