I’m trying to configure DeviceHub to connect to my local development instance and I’m getting this error: Failed to connect to http://localhost/siteName/signalr/hubs/deviceHub server

I can’t find any related posts or information.

@darylbowman make sure you have the devicehub with same exact version as your local instance. If it is different uninstall and install the corresponding version/build and retry

    Depending on your build, it was a bug in 22R2 and 23R1 until like 23R105 or something like that.

    I believe this occurred after an upgrade. I installed the correct version and it resolved.

      ​@darylbowman Thanks. I resolved it by giving Device hub permissions and run as admin and then removing the Tenant in case i have only one.
