URI specified in the ApplicationDescription does not match the URI in the Certificate

This means either one of two things:

  1. The URI in the endpoints truly doesn’t match the URI in the certificate.
  2. The URI in the certificate has characters in it that make it an invalid URI, usually a space that hasn’t been URL-encoded, and when the comparison happens it fails because this invalid URI got parsed into a null value by that point.

In either case, you can either connect without security or fix this on the server somehow. Re-generating the certificate on the server might help, but if not you may need to call Rockwell about it.
