I’m getting the following error on all SQL tiles following the 3.4.1 update:

Failed to select fields from a signed JSON request. This endpoint only accepts requests which have been authenticated (signed) by the server

I have run an IIS reset and rebooted the server but I’m still getting the same error.

Even a new tile with the example data warehouse query suffers from this.

Does anyone have any ideas?
