Hello everyone,

I'm using UAExpert to communicate with a S7-1500 and I did it successfully with user/password authentication mode. The problems began when I tried to communicate via certificate, I used the own certificates from UAExpert, introducing the path of each one, public and private key. Do anybody know the reason of the problem? UaExpert bring me back 'BadConfigurationError'.

Thank you!

Hi,

not sure how you have created the user-certificate (you can not use the application instance certificate, you must have user certificate). Anyways, you should check the UA server if it supports the user-certificate token for the endpoint. To do so you connect with UaExpert and open the "ServerDiagnostics" Plugin, with that you can see the endpoint description as returned by the server, here you can see if at all, and on which endpoint the server supports the user-cert token for authentication.
