ATT issue connecting to Microsoft Teams and LinkedIn

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?

Thanks for your advice.

The message says:

This site can’t be reachedwww.linkedin.com took too long to respond.

Try:

Checking the connection

ERR_TIMED_OUT

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

tracert www.linkedin.com

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.

Thank you for this information!

We just transitioned to teams internally and I hate it. 

Ah, an online traceroute would show from their server to the MS server, and that doesn't tell you much.

Your traceroute shows a huge jump in latency on your first hop.  Your first hop is in AT&T's wireless space.  Which AT&T Internet service do you have, i.e. do you have Fixed Wireless, AT&T Home Internet, FTTP, or FTTN?

Secondly, do you upload large amounts of data (online backup, P2P sharing, live streaming, etc.)?

Hi. AT&T is blocking sites. We set up a VPN and now the sites work fine. Do you know who to contact from AT&T to report this?

Thank you for letting us know that LinkedIn is being blocked, @sbumpusb2.

We'll submit your feedback to our support team, so they can work on a resolution. If you need help with anything else, don't hesitate to reach back out and let us know.

Thank you for visiting the AT&T Community Forums.

Thanks Aminah!  We have a Georgia IP address and LinkedIn and Teams are both being blocked by AT&T.  This has caused issues with our work from home as employees working from home. We are considering switching ISPs if this cannot be resolved. Is there a number where I can call you or your team directly? I appreciate your help.
