    Hi Guys,

    I've been unsing deepin since several years now, and I'm still amazed!

    Since last upgrade to Community Edition 20.4, I cannot connect to my work VPN any more (via VPNC) though. In system logs (/var/log/messages) I see following entries when starting my VPN connection:

    Why does NM automatically "deactivate" the connection in the same second it just came up (timestamp [1646232414.2198] above)????

    I can't find any reason, nor error. After starting VPN connection, I don't have "tun0" interface, or sometimes I do have, but without IP address...

    In versions prior to v20.4 (even with 20.3) I didn't have this issue...

    Where can I start checking? All packages are up to date (kernel is v5.15.6-amd64-desktop).

    Thanks a lot and keep going on with this great work!

    CU

    Sorry for the inconvenience, the VPN problem has been fixed in the current internal test, you can add an internal test warehouse to experience it, refer to: https://bbs.deepin.org/post/232826

    At present, the internal testing environment is relatively stable, and a new version is expected to be released at the end of the month 😁
