Hi Andrii, > I see the problem on IKE side, but don’t know how to debug and fix it.
The log tells you _exactly_ what the problem is: > 12[ENC] parsed INFORMATIONAL_V1 request 2090615229 [ HASH N(NO_PROP) ] > 12[IKE] received NO_PROPOSAL_CHOSEN error notify The peer doesn't like the crypto proposal sent by the client. So fix the `esp` setting in the config (maybe you have to enabled PFS by adding a DH group, ask the other server admin for the correct algorithms). Regards, Tobias
