WSJT-X: Error Loading LotW Users Data

When startin WSJT-X v2.0, an error is shown saying: “Error Loading LotW Users Data”. Dit is due to Windows systems not hndling Intermediate CA’s correctly when retrieving the LotW user data file thats been served from a secured website.

The solution is simple.
  • Start WSJT-X and click on file -> Open log directory.
  • Than, manually download this file and place it in the WSJT-X log directory.
  • The SSL error should be gone now.

      Glyn, the error you cite is not due to Windows SSL certificate handling. WSJT-X does not use the Windows proprietary SLL handing, instead it uses the OpenSSL library and the error is usually due to the user having not installed the OpenSSL libraries as directed by the WSJT-X User Guide. Since WSJT-X v2.0.1 the application no longer tries to fetch a LoTW Users file from the ARRL on startup so this error will not happen unless the user elects WSJT-X to fetch the file.
