Client v9.1R2 disconnects after 5-10min on Ubuntu 20.04
I have a client version 9.1R2(69) running on Ubuntu 20.04 that keeps disconnecting my vpn connection after 5-10min. It works fine up until then.
I'm wondering if this is a problem with some tcp keepalive or is it the NetworkManager causing this to be disconnected since the tunnel created (tun0) is not managed and needs to configured as to be ignored by the NetworkManager.
Anybody that have some experince or knowledge on how to resolve this ?

firstname.lastname@example.org Sounds like a control channel disconnect caused by some ISP or Firewalls if the TCP channel doesn't send any data for more than 5 to 10 mins, which is true in the case when VPN connection is using ESP data channel i.e. TCP control channel will be only having keepalives sent back-forth b/w client and VPN server.
Do you see ESP payload sent out from your physical interface? If possible, please switch the VPN data channel to SSL (config change on the server side) and check the behavior.
