I'm on latest created 6/10/26 on Synology NAS- Deeplinks with Osprey's. I haven't seen this issue.
Super weird. Are you on the latest CDVR update?
2026.06.29.0212
I would think if cdvr was doing it, it would show up in the support logs.
It may have had something to do with having 10 ospreys and running CH4C on 3 encoders. I just reset my DirecTV password and re-logged into all my boxes and while they still stall if I immediately tune without a pause after waking, which I kind of expect at this point, so far I haven't had that splash screen come up and interrupt yet. 
I think they only allow 2 streams via browser
edit; I just tested, had a stream running in firefox, chrome, and edge. I was thinking of this
so with ch4c it's possible the multiple sandboxed chromes are causing a hickup
I honestly think CH4C got my account sort of in a weird state where it maybe got flagged internally.
From what I could tell from looking at ADB on the boxes with Claude, it appears that Widevine L1 kept getting torn down very early into the stream at random intervals. Since resetting the password, it seems like it's slowly improving, although not perfect, but it's super duper weird. Honestly, it was fun playing with CH4C, but given I have 10 Ospreys and two ENC5 V2s, I really don't need to use it. Especially if there's a risk of it causing issues with my account because I have so many devices attached. It is a fantastic tool though. I really do like it.
I only think it's that because I noticed CH4C wasn't working, so I went in and reauthorized it, and like a day or so later, I noticed things were acting weird.
