Worked fine but a couple of days ago - I can no longer connect....
On the client side I use

авг 22 23:15:09 thinkpad nm-l2tp-service[18637]: g_dbus_method_invocation_take_error: assertion 'error != NULL' failedOn the VPN-server side there are the following error messages:
ISAKMP-SA established server_ip[4500]-client_ip[20406] spi:4db152d55bba4373:ee206901a7e5a073
the packet is retransmitted by client_ip[425].
respond new phase 1 (Identity Protection): server_ip[500]<=>client_ip[425]
client_ip peer sent packet for dead phase2The funny thing is that connection worked fine for some time and all of sudden stopped working - no updates and no changes have been made.
Any help is appreciated!
