Authenticate/Decrypt packet error: missing authentication info in OpenVPN, Peer to Peer (SSL/TLS only :/ )
-
Hello to all,
i'm facing an issue with on of my Peer to Peer VPN.
I manage multi site pfsense and i start to migrate SharedKey VPN to SSL/TLS because first one is deprecated.
So far it went smooth for the most of them, bu i have a tunnel between 2 pfsens that are very far from each other, the first one is in Singapour and the other one in France.
The Sharedkey tunnel is working absolutely fine, but when i switch to SSL/TLS mode,i get "Authenticate/Decrypt packet error: missing authentication info" on the client side, and the tunnel keep reseting, it stay connected just few seconds...
I made some research and find some posts that suggest this could be related to bad connection and MTU... and i don't know how to handle this.
I tryed to switch to UDP instead of TCP, but i getting more errors, so went back to TCP.For now i switch back to shared key because tunnel work fine in this mode.
Any sugestions / help will be much appreciated.
I must admit i m not a pfsense pro, not compltely noob as well, still learning a lot.
Regards

I answer my self it could be usefull for others:
After few try, i change the role of pfsense and set the server on the slower side, now the tunnel is stable. :)
