connection error with svnsync during SSL communication

Question

I am on a Windows Server machine and trying to make a mirror of an SVN repository using svnsync (version 1.8.1 for win32, not installed, just extracted and svnsync called straight from the bin folder). The server requires a client certificate to grant access (https).

The messages I get from svnsync are

1. E120171: Unable to connect to a repository at URL https://external.svnserver.com/myrepos
2. E120171: An error occurred during SSL communication.

I can check out the repository via TortoiseSVN, providing my certificate as pfx-file.

I assume I have to provide the certificate for the svnsync command as well. Question is how? Or are there other options to mirror an svn repository?

What version of svnsync are you using and do you get the error immediately or does it happen part way through a sync? – Antimatter

I put more details into the question. I use version 1.8.1 and the error appears after about 2 seconds running svnsync init, no data transferred. – Varix

Log into the server, do a checkout - just so it asks you for a certificate - accept the certificate, then go back to the machine you were working on and try running the command with the --trust-server-cert option – Wanids

@SameerSingh thanks for the suggestion, it didn't worked though - isn't it that I have to present my certificate to the server such that it grants access (rather than the other way around)? – Varix
