Hello all ,
I want to roll out MS teams to use company wide since we have included in our office365 bundle . I have created a small user test group before company wide push. My issue is that in some of the users i am facing the issue where the desktop app will not connect to any Audio/Video meeting with the error "Sorry we couldn't connect you". Others it works fine.
The users can join all meeting fine via a browser though.
I have checked event logs and the only error i see when joining a meeting is the 4227 error TCIP .
I have tried reinstall ms teams , restart pc , check drivers nothing.
I havealso tried manual install from downlaoded msi and exe still same issue.
Can anyone pelase help ?

We're experiencing the same error for any call from a call queue to some users. If they login to a fresh machine with Teams, then they don't have the problem. We have NOT tried the reg key fix that was suggested here yet. With so many people experiencing, seems like a bigger issues with the Teams desktop client itself.

I encountered this today with a user.
He had been on a Teams meeting earlier and had left his Bluetooth speakers on & connected to the laptop.
He got the "Sorry we couldn't connect you" Teams app message when he tried to join a later meeting.
He changed Teams to use system speaker, then he could connect.
He was then able to change Teams to use the Bluetooth speakers.
I suspect that signing out and back in to Teams would have done it too - to use system speakers instead of Bluetooth.

FWIW I was able to resolve this for me by Sign Out and back in again. A password change may have affected it. Note that restarting the app was not enough.
This worked great for me, thanks for the advice.

@Andrew Matthews Hi Andrew, if you are using a VPN the IP address is constantly changing each time you connect. How do you enter in the IP address for IPv4 with IP address changing?

@TechEng The web services for Microsoft Teams use a defined range of IP Addresses. There is a public document with the ranges on docs.microsoft.com.
If you are talking about changing the TCP/IP port ranges. That should be a standard part of your build on Windows 10. The settings in the link that I provided do not hard set the client IP address, they change the dynamic port ranges to maximise the number of ports available.
