Sophos connect Client a lot of "received IKE message with invalid SPI" - MR10

StefanS

Hi there / Support,

After upgrading from MR9 to MR10, connecting with "Sophos connect client" to the firewall is very unstable.
There are several error messages in system like this:

- IKE message retransmission timed out

- received IKE message with invalid SPI

This is really bad because, we just want to roll out the new VPN client.
Is this a bug or feature?

Thanks for any help.
Stefan

    Hi  

    Did you observe that when you receive these messages in Log viewer, are you facing any disconnection or VPN communication issue?

    I would request you to share your observation in details, It would help us to assist you better.

    Hi Keyur,
    We can say the following.
    We have been using the "Sophos connect Client" (latest version) successfully for about a week rolled out and put into operation.
    With the MR9 saw no connection problem, only since last night after upgrading from MR9 to MR10.
    The colleagues complain that the VPN tunnel is not always successfully established when the first connection attempt is made.
    In this case, the "Sophos connect Client" makes several new connection attempts until it is ultimately successful.
    Similarly, we see said error message in the system log file:

    - IKE message retransmission timed out

    on the client site:
