OpenVpn on Ubuntu and Sophos SSL VPN client restarting

I have an Ubuntu user who in the past hasn't had an issue using the code below to connect to our SSL VPN

openvpn3 --config Profile.ovpn

but for the past few days when he tries to connect the client just keeps restarting the connection. On the SSL VPN logs I see the following after he connects and the routes are set.

subnet,ping 10,ping-restart 120,route ### (status=1)
2022:01:06-11:49:17 firewall openvpn[3239]: user/###.###.224.27:53160 Connection reset, restarting [0]
2022:01:06-11:49:17 firewall openvpn[3239]: user/###.###.224.27:53160 SIGUSR1[soft,connection-reset] received, client-instance restarting
2022:01:06-11:49:17 firewall openvpn[3239]: id="2202" severity="info" sys="SecureNet" sub="vpn" event="Connection terminated" username="user" variant="ssl" srcip="###.###.224.27" virtual_ip="###.###.2.4" rx="4013" tx="4169"
2022:01:06-11:49:17 firewall openvpn[3239]: PLUGIN_CALL: POST /usr/lib/openvpn/plugins/ status=0

We were able to successfully connect using

openvpn --config Profile.ovpn

Is openvpn3 no longer supported on the UTM? Is there something that has to be changed in the config files or below? If I do change settings below will all VPN users have to re-download their profiles?

  • hi,

    sorry, no solution or hint regarding your problem.

    But i would try to change some settings.

    Authentication SHA1 is not current/secure.

    ... and i am not a friend of TCP/443 as nearly every Firewall/AV/Endpoint-protection try to decrypt this traffic.

    Most success/least problems with TCP 1194.

    ... any YES, if you change one of these settings (except key lifetime) all users has to redownload or change the config file.
