Roku remote calls work but create log errors

My setup is a hassio install in a vm, on a vlan. I have roku’s on another vlan so discovery does not work. Rules are set up to allow the hassio install talk to any other network. The roku’s are defined in configuration.yaml and service calls will work, turning them off/on, changing sources, etc. But there is an exception in the logs whenever I call a service to them. It causes scripts to stop execution before completing. I can use curl and make command line ecp calls directly from the hassio command line with no errors. What is causing this error?
