ATT issue connecting to Microsoft Teams and LinkedIn

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.

I do not believe that AT&T is blocking the sites.  I believe that the sites (or their network) are blocking you based on your AT&T-provided IP address.

If you can prove otherwise, please explain.

BTW, one reason I do not believe AT&T is blocking these sites is because I use them routinely on my AT&T connection.

We understand your frustration with your work getting interrupted, sbumpusb2.

We don't have a direct line to call, as we primarily operate on the Community Forums. As JefferMC stated, it seems that the webhost of those websites is blocking your connection. In that case, you would need to reach out to their support team to be whitelisted and able to access those sites.

If you would like for us to dig deeper into this, we can send you a Direct Message to see what we can find. Let us know what works best for you.

I'm having this exact same issue on my Galaxy S22 Ultra on AT&T where Teams and LinkedIn connections drop after some amount of time on mobile data.  The connections are restored immediately when I connect to wifi.  This needs a solution ASAP.

@Jtriplett38 you are describing basically the opposite of the OP's behavior.

We want to help with a solution to what you're experiencing with your mobile data, @Jtriplett38. 

Below are a few recommendations we'd like you to try to help improve your connection on Teams and LinkedIn: 

Power Cycle/Restart your device:

• Restarting your device is one of the most common fixes for connection errors. 

Toggle Airplane Mode:

• Most devices have the option to place your device in airplane mode. Airplane mode while designed to power down while in the air, can help sync your phone to the nearest tower. 

Reset the network:

1. From the home screen, tap the settings icon.
2. Scroll down and select General.
3. From the general screen, scroll down and select reset.
4. You will be taken to the reset screen. Select Reset Network Settings. Resetting the network deletes saved Wi-Fi Networks. 

In addition, you can check out the many causes of weak signals to learn why you may be experiencing a drop in your connection. 

If the above steps do not work, try our Wireless Support page. Our Device How-To also has a lot of great information!

Please keep us updated on how this information works for you! We're happy to take a more advanced approach if needed.
