every week we have to restart the QlikSenseRepositoryDatabase due to unavailabity of the web service hosted by the proxy node of the infrastructure:
in the web browser the users see the error "ERR_TUNNEL_CONNECTION_FAILED";
in the proxy log there's only the error below, repeated hundred of times:
Error when accepting client connection: 'A call to SSPI failed, see inner exception.'
The only working procedure is to restart the server or simply the service mentioned above, but it will be a big problem for us soon (the production will serve so much users than now in a few months).
thanks in advance for the help
