Windows Phone certificaat foutmelding

There are two possible solutions for this:

  • Recheck your SSL certificate using the Xolphin SSLCheck; if this is not the case, follow theĀ correct manual to do the installation.
  • Are the root and intermediate certificates correctly installed, but does the error message remain? Double-check the Date & Time settings on the phone and correct these if needed. Incorrect Date & Time settings could cause one or more certificates not to be trusted and does not relate to the server-side settings in any way.
