Hub 5 crashes from RTSP stream
Since the hub 4 to hub 5 swap I've began experiencing a fault which takes the entire internet down. At first it was difficult to identify the cause. From my personal usage, it occurred when playing the game VRChat and I assumed that it was related to the game. However I've been working on narrowing down the cause and it seems worse than that. First, I called an engineer out to check power levels (it's always "check power levels!") To be safe the virgin engineer checked and reduced power levels them so they're now certainly within range. However, the problem persisted. Errors in the network logs are always the following: 16-04-2023 00:22:53 critical Cable Modem Reboot due to RG crash 16-04-2023 00:18:22 critical SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1; 16-04-2023 00:18:11 critical Cable Modem Reboot due to RG crash 16-04-2023 00:13:48 critical SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1; This does not appear to be an isolated issue with the hub 5. The following similar issues were found: https://community.virginmedia.com/t5/Gaming-Support/Connection-issues-with-VRChat-RG-crash-Packet-loss/td-p/5303479 https://community.virginmedia.com/t5/Gaming-Support/SYNC-Timing-Synchronization-failure-while-in-vr/td-p/5291040 The pattern that I noticed was that this crash occurred when I was in VRChat worlds playing an RTSP music stream. Music streams are popular in this game. After the internet goes down, If I left the game client open, even as I had disconnected from the instance (and all other players in it) the hub 5 would still keep crashing because the stream was still trying to load in my own (private) world. In the latest incident the music stream was an RTSP stream on TCP 554. The URL host being: https://stream.vrcdn.live After noticing this pattern I tested a stream using this URL in VLC media player completely outside of VR. It crashed the hub 5 with the exact same symptoms. I tested an HTTPS .ts of the exact same stream and it loaded instantly and ran fine. This seems to be entirely due to the RTSP stream. Please advise. If this is a flaw with the Hub 5 is requires a critical fix. A protocol-phobic router is, unsurprisingly, a BIG problem.
