[Error] Microsoft.AspNetCore.SignalR.HubConnectionContext Failed connection handshake

Hi There,

I have universal dashboard community installed (ver. 2.3.2) and works on IIS 8.5, the dashboard so far is functioning properly and with no issues.

i have decided to use logging as error level.

am also using IIS basic Authentication were users have to enter the credentials of an AD account to login .

looking at the logs file when using the dashboard i saw the following message keep recorded

[Error] Microsoft.AspNetCore.SignalR.HubConnectionContext Failed connection handshake

even though am not experiencing any issues using the dashboard, i have decided to post it here if there is anything i need to configure at my end to fix this error.

Kindly provide a step by step solution to address this error if you are aware of it and why its happening.

Thank you.
