ADFS - Blank page with certificate auth

Question

Hey,

I have a wired problem with my adfs (v3 - Server 2012 R2) system.

I open the site https://myadfs.com/adfs/ls/IdpInitiatedSignon.aspx to test the authentication. It works perfectly with the form based auth.

After I switch to the certificate auth - the authentication works but I get a redirect to a blank page ...

No errors in the log files and debug event log.

I used a self signed certificate with a public accessible AIA and CDP.

The FIPS compatibility was disabled.

Any suggestions :-) ?

Thank you !!

Edit: 44349 Port is open ;-)
