Hello

We have an issue with Kaspersky VPN

Please check detail below
 

[A515U][DSH] [BUA4/PR] [Always] [Device Info] DUT A BUA4 IMEI:358338560000343 MDN:19132201933 (MSG APP: 11.5.10.372) REF G981U S/W: BTK2 IMEI:351847110620688 MDN:19139571664 (MSG App: 11.5.10.313) Kaspersky VPN Ver: 1.37.0.65 AdGuard BPN Ver: 1.0.267 [Pre-Condition] Download Kaspersky VPN and adGuard VPN app and install  [Procedure] 1. From DUT A, turn Kaspersky VPN on. 2. Send/Receive Chat and FT between DUT and REF. 3. From DUT, turn VPN off 4. From REF, turn VPN on. 5. Send/Receive Chat and FT between DUT and REF. 6. Observe and repeat above steps with AdGuard VPN.

When connecting VPN (kaspersky) in the same VPN framework, the VPN server is determined according to the policy of the corresponding app and tunneling is configured. 01-20 13:08:07.852  5345 18574 D UploadFileTask: java.net.SocketTimeoutException: SSL handshake timed out happened. Retry Upload Task. The problem is that the task requested only in DUT is not responding. In the state where the VPN is connected, the network may be affected by the corresponding VPN server (kaspersky). Timeout occurred because the network response did not come when the VPN was connected only to the DUT. The connection to the VPN server requires confirmation of the 3rd party app with the policy of the app.
