tinc 1.1pre10 "failed to decrypt record" on Windows client

[Lance Fredrickson]

I also have not been able to get Windows clients to play with Linux ones on
tinc1.1pre10. I sent an email February 11th describing my issue, to which
the maintainer responded. For the time being I'm using 1.1pre9 and hoping
the next release is more Windows friendly.
