It's likely not the same error. Post the LastErrorText for v9.5.0.58. I suspect it is different.

The problem is this:

Unable to agree upon server-to-client MAC algorithm.
Unable to agree upon client-to-server MAC algorithm.

The solution is to make the server accept more typical and commonly used (but also very secure) MAC algorithms, or to wait for Chilkat to implement a few of these other MAC algorithms..

I added support for hmac-sha1-96, so it should work now. Here's a new build:

Wow, thanks a lot, that was quick.

The connection works. But there is a problem afterwards. Mayby a probem with hmac-sha1-96?
