    I can confirm the same problem here.  Our company is behind a VPN in addition to a HTTP proxy.

    • When not connected to the VPN and directly on the internet, Teams calls work correctly in both Chrome and the desktop client.
    • When I'm on the VPN and behind a corporate proxy, Teams calls work correctly in Chrome but NOT on the desktop client.  The error message is "Sorry, we couldn't connect you"

    Both scenarios work correctly on Windows 10.

     

    I can see that Teams uses UDP while making the calls.  Running a tcpdump, I could see the traffic going through with Chrome but saw no traffic at all with the desktop client.

     

    I've resorted to using Teams in Chrome but it's not ideal as some features (e.g. test calls) are missing from the web version.

     

    I've tested this on many Linux varieties (but most notably the latest few releases of Ubuntu and Fedora).  I've always used the very latest version of the Teams client.

     

    My current test environment which fails is: Ubuntu 20.04 with Teams 1.3.00.5153

     

    Pretty please Microsoft friends, help us out! 🙂

      For me it worked out if I set the http_proxy variable and then start teams with teams --proxy-auto-detect. This is working with Teams Version 1.3.00.16851 (64 bit) at least on my side.

        hdesk Thank you so much!  I just tried the latest version and everything worked perfectly without adding any extra CLI parameters!  It appears that maybe this has been fixed!!! 🙂

    This seems to be still an issue.

    Have to work with Teams in my company but can't. Tested with two different proxies (one with auth one whithout). Without Proxy outside the company VPN with the same device it works.

     

    Steps2reproduce:

    1. in company VPN with enabled proxy
    2. freshly installed .deb package version teams_1.3.00.5153_amd64
    3. started the app
    4. logged in
    5. authenticated on proxy
    6. text chat works
    7. video call -> We couldn't connect you
    8. voice call -> We couldn't connect you

    System informations:

    • Ubuntu 19.10
    • Gnome 3.34.2
    • teams_1.3.00.5153_amd64

      Hi, this is kind of important for orgs with linux who would like to use teams. Which channel is best to raise visibility/track progress for this issue?

      thanks
