"Encryption got out of sync"

Sun Feb 07, 2010 4:08 am

Often, when I connect PPTP from Windows to Mikrotik4, it immediately disconnects after connection. Usually, I can immediately re-connect and it is fine.

Once I am connected for more than a couple seconds, it NEVER drops the connection.

If it drops the connection, it is ONLY right after connection. If it stays connected for more than 2 seconds, then it will stay connected forever.

This is using a user inside the Mikrotik, not radius.

Here is the log:
user: authenticated
user: connected
user logged in, 10.10.10.10
user: using encoding - MPPE128 stateless
user: logged out, 3 1552 612 26 16
user: terminating... - Encryption got out of sync

I can confirm that the problem still persists in 6.30.2.
It is easier to reproduce when connecting from Apple clients.

You must have extensive packet lost on that link where tunnel is running on. I can't see this happening here in my network
