I've attached the syslog for easier viewing. ** Attachment added: "syslog.txt" https://bugs.launchpad.net/network-manager/+bug/1849930/+attachment/5300267/+files/syslog.txt
** Description changed: When I add only one L2TP VPN profile to gnome-control-center's Network > - VPN setting, it works fine. + VPN settings, it works fine. However, if I add a 2nd L2TP VPN, the 2nd L2TP VPN, not only doesn't work, but it corrupts the first L2TP VPN so that it too stops working. Furthermore, if I remove 2nd L2TP VPN profile (that corrupted the first L2TP VPN) this does NOT repair the corruption to the first L2TP VPN, it remains corrupted. Additionally, removing all VPN profiles and re-adding the first one back, doesn't repair the corruption. Rebooting and adding them back doesn't work either. The only thing that works, that I've found, is completely reinstalling Ubuntu 19.10. Please advise better workarounds than reinstalling. Here's what's in the syslog on a failed VPN Connection attempt: Oct 26 02:58:35 workstation5 NetworkManager[1241]: <info> [1572076715.5632] audit: op="connection-activate" uuid="1942cf95-93b1-4e74-a44a-947a46bffb5a" name="L2TP VPN1" pid=3531 uid=1000 result="success" Oct 26 02:58:35 workstation5 NetworkManager[1241]: <info> [1572076715.5702] vpn-connection[0x5642f421c750,1932cf95-91b1-4e85-a44a-498a56befb5a,"L2TP VPN1",0]: Started the VPN service, PID 7273 Oct 26 02:58:35 workstation5 NetworkManager[1241]: <info> [1572076715.5747] vpn-connection[0x5642f421c750,1932cf95-91b1-4e85-a44a-498a56befb5a,"L2TP VPN1",0]: Saw the service appear; activating connection Oct 26 02:58:35 workstation5 NetworkManager[1241]: <info> [1572076715.6566] vpn-connection[0x5642f421c750,1932cf95-91b1-4e85-a44a-498a56befb5a,"L2TP VPN1",0]: VPN connection: (ConnectInteractive) reply received Oct 26 02:58:35 workstation5 NetworkManager[1241]: Stopping strongSwan IPsec failed: starter is not running Oct 26 02:58:37 workstation5 NetworkManager[1241]: Starting strongSwan 5.7.2 IPsec [starter]...
