I recently installed NC, everything went fine. Connection via browser no problem, connection to OnlyOffice went fine. But i get an error when i try to connect with the most recent Desktop Client on Windows 10 (3.1.2). NC is 20.0.6.
This is the error:

As said, login via browser without any problem.
SSLchecker (SSL Checker) says everything with the certificate and the certificate chain is fine.
Any idea ? Thanks for any help.
