Roku Issue

I have a new Roku Ultra. Auto Discovery found it and added it to the system.  When I try to send a command, I get the following message:24/05/2024 16:35:16.35 · DEBUG · Server.doCommand - AV|31~Remote~Down24/05/2024 16:35:16.35 · DEBUG · Roku.doCommand - Cmd=[31~Remote~Down] Client=[dashboard-fx-ghg8]24/05/2024 16:35:16.35 · ERROR · Roku.PostDataAsync - An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.Any Idea why?

It looks like it's fixed. I needed to reboot the server for it to start working.

FYI - My Roku Ultra didn't play nice with other devices (CEC Stuff). Turning it off in the settings helped but did not eliminate the issue. The solution was a HDMI CEC blocker from Amazon.
