     I am getting below errros in our logs:
     Message : Error sending system message to URL: http://host1:12600/Sitefinity/Sitefinity/Services/LoadBalancing/SystemWebService.svc/HandleMessages; HTTP method: PUT; Host: 'host1:12600'

  • Hi,

    Judging from the provided information "Sitefinity" is not a virtual in your set-up, can you please try to remove the "/sitefinity" part of the url settings in your project, save the changes and restart the application.

    The issue seems related to that feedback item:
    If so, this is just a warning that you see during the site initialization, as all the notes are not available at the same time but you should not have any issue after that.
