<!-- BUG REPORTS THAT ARE NOT FILLED OUT COMPLETELY WILL BE CLOSED AUTOMATICALLY WITHOUT WARNING AND WILL NOT RECEIVE A RESPONSE. THE FORM IS HERE FOR A REASON. :). -->
<!-- Please ensure you read the documentation before creating a support request, especially the Troubleshooting page. -->

**Describe The Problem:**
I am no longer able to stream from my cameras to some iOS devices iPhones and iPads running 14.4. I get an error message that says: "No Response: This camera is not responding." It works fine on some of my computers and not others on the same local network. The iOS devices are also on the same local network. RTSP is enabled on all of the cameras.

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
Open the Home App in iOS and then tap on the camera thumbnail view to bring up the live stream.

**Logs:**
<!-- In order to be helpful, include the relevant logs from Homebridge, if applicable. -->
