We are developing cms on SiteFinity 8.2 and deploying application on webfarm. It has two hosts with port on which application is deployed. We have done setting as per documentation for load balancer.

 Url of the application:

 Settings for hosts in Advanced Setting -> System -> LoadBalancing-> WebServerUrls are like below:

 We have also added below values in Administration -> Settings -> Advanced -> Security -> SecurityTokenIssuers:


 and for RelyingParties we have below values:
 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'

 Inner Exception
 Type : System.Net.WebException, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089
 Message : The remote server returned an error: (401) Unauthorized.

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.
