Acquiring the networking information from the DHCP server failed

Post by desperados » Mon May 14, 2018 2:17 pm

i've softether installed and working since 2-3 years
this afternoon, i cant connect any more, in logs i see:
"2018-05-14 16:14:25.867 L2TP PPP Session [95.237.92.111:1701]: Acquiring the IP networking information such as subnet mask and the default gateway information from the DHCP server.
2018-05-14 16:14:30.872 L2TP PPP Session [95.237.92.111:1701]: Acquiring the networking information from the DHCP server failed. To accept a PPP session, you need to have a DHCP server. Make sure that a DHCP server is working normally in the Ethernet segment which the Virtual Hub belongs to. If you do not have a DHCP server, you can use the Virtual DHCP function of the SecureNAT on the Virtual Hub instead.

2018-05-14 16:14:31.332 Connection "CID-16" terminated by the cause "The VPN session has been deleted. It is possible that either the administrator disconnected the session or the connection from the client to the VPN Server has been disconnected." (code 11).

2018-05-14 16:14:31.332 The connection with the client (IP address 95.237.92.111, Port number 1701) has been disconnected."

Do you enable the localbridge?
If so, is it tap mode?
