Hi Tuomo,

Thank you very much for your answer.

My last setence was malformed (I meant 'like if the key was invalid') 
and in fact I also realized in between that when you change the PSK 
file, you must restart the dameon in order to have it taken into 
account. With that test (removing the key file), I saw a different 
behaviour as expected (no suitable key found). I have also requested a 
contact for the other part (VPN other side) to tell me what's wrong in 
their logs. Still waiting for an answer. Will follow up if any news. 
Many thanks.
