Harmony hub no longer able to control/IP connect with Roku Premiere+

As of yesterday my Harmony Hub has seemed to be unable to connect to my Roku Premiere+, when I try to control the Device on the app I get the error message above. When I select Fix It it seems to go through the motions of reconnecting to the Roku but when it concludes, nothing has changed and the error message pops again.

I've tried updating the app software, and I've tried removing the Roku device and re-add it, but no luck. Is there any sort of manual configuration I can attempt?
