Unable to open Plumsail

I am receiving an error: Unable to check the supported version of the client application. It was working fine yesterday. Ran a repair, restarted computer. Still cant get Plumsail to open.

System.Net.Http.UnsupportedMediaTypeException: No MediaTypeFormatter is available to read an object of type 'SolutionVersion' from content with media type 'text/html'.

Hello @ChrisEaker,

There seems to be something wrong with the deployment of the solution. Please, check the following:

  1. Make sure there is enough memory on the server
  2. check the application status in the Central Administration. If there is an error, try to re-deploy the solution. Please follow the instructions:
  3. Make sure that https are configured correctly for the server.
