Similar behavior on my tested devices Ultra 4660 (OS 11.5) and Express 4k+ 3941 (OS 11.0), so not something particular to you.
Seems like UCFKnights.tv (SideARM Sports) is having an issue.
I don't see Roku listed on the site under the Watch/Listen category so either no longer supported or just having some temporary issues. http://ucf.sidearmsports.com/
Maybe try contacting them under their help page and see if they can provide you some more information.
