  • Those are logs from the client, Christian.  Please show the log from the UTM for the corresponding time frame.  Also, a picture of the 'Advanced' tab in 'SSL VPN'.

  • Mon Sep 13 08:33:02 2021 Authenticate/Decrypt packet error: packet HMAC authentication failed

    This is usually when the client and server aren't sharing the same cipher authentications.  They need to match, i.e. 

    cipher AES-256-CBC

    The ciphers have to match on both sides.
