received NO_PROPOSAL_CHOSEN error notify

Hi guys,

Imkep getting the following error trying to connect to one of my XG: received NO_PROPOSAL_CHOSEN error notify

I have the exact same configuration on another XG and it works fine. The pdf document does mention the error but says: refer to admin. No admin here.

Any experience with this? The client is 1.2.

  • Hello,


    Make these two changes to the .tgb file. 

    1) Look for this line: Transforms = AES256-SHA2_256-GRP2 and replace it Transforms = AES256-SHA2_256-ECP256.

    2) Look for this line: Transforms = TGBQM-ESP-AES256-SHA2_256-PFSGRP2-TUN-XF and replace it with Transforms = TGBQM-ESP-AES256-SHA2_256-PFSECP256-TUN-XF


    Now import the modified .tgb file and try to connect again.

    If you need to use the .scx file, then import the modified .tgb file in Sophos Connect Admin and make the change you need, save it and import the modified .scx file.


    Please let us know how it goes.

    Hi Ramesh,

    Worked fine, thanks a million. Out of curiosity, why did this occur in the first place?

    Thank you for letting us know. This is a bug in SFOS. Hence we had to use this work around in the client policy.
