Problem with VPN
From: Teamviewer corporate (Mativesi Group)
Target: Teamviewer Host (DeFra water)
From some computers i am able to make VPN connection, but others not. (2 computers are not other 2 are able to connect).
Edit:
Group 1 - Teamviewer Host most up to date and version 15.39.5 I updated the outdate to uptodate.
Group 2 - Teamviewer 15.39.5 - 2 computers
Group 1 can connect with each other and with Group 2.
But Group 2 cannot connect Group 1, but can connect with each other.
From most updated Version 15.39.5 corporate licence i am NOT able to connect.
But version 15.39.5 i am able to connect.
I want to use most updated computer not old warehouse one.
Other facts:
IP get assigned in all cases. Cmd ping fails. Only few cases first ping goes through but then others get timeout and connection not returning. While in second computer all pings go successfully with good TTL and 100% reproduceable.
What is causeing this issue?
Pinging does not help.
Disableing ip6 does not help.
Reinstall driver or teamviewer does not help.
Reinstalling to 32bit Teamviewer version did not help.
Installing older version does not help.
Going through windows functions and makeing them same in both computers did not help.
I looked into log files of both computers and found difference:
2023/03/07 10:34:37.292 5344 6864 S0 SecureNetworkConnection::SendCallbackHandler(): [ remoteID: *id replaced by me* connection: *replaced by me* remoteConnection: *replaced by me* ], Error: SecureNetwork (Connection not found)

If needed i could add more log entries. Also only in succesful connection :
2023/03/07 10:31:35.787 5380 8444 S0! CStreamManager[11205]::IncomingStreamCommand(): anticipating streamID=6!
Both connections have:
The point where to connection goes has following error:

Ping increases received packets, but return is timeout.
Edit 2:

There is time difference ^^ 1 hour as clocks differ between computers.

I reduced the number of problematic computers by doing following:
Networks Sharing Center>>
1. Turn on network discovery on public and private networks.
Windows>>Services>>Start>>
1. IPsec Policy agent
2. Ike and AuthIP IPsec Keying modules
Then try to make VPN connection.
