Hi,
I had Chromecast issues and now, I've found out something, that I didn't realize I'm In-gearlier.
When I'm In-game, sometimes my stream freezes and crashes. When I press the Stadia button on my controller, I can still navigate through the Stadia in-game menu without input lag, so my controller has a working connection. After 20-30 seconds, my CCU says "link a stadia controller" and shows me the pairing button combo, even if my controller is still connected and didn't disconnect. If I'd try to restart the controller to repair it, it wouldn't be able to reconnect to my device and even if it would connect, the "link your Stadia controller" pop up wouldn't disappear.
Usually, I factory reset my CCU+Controller or restart it when this happens, but this time I opened the Google Home app and pressed the "quit stream" button. My controller stayed connected, despite Stadia was denying it. When Stadia closed, I could simply restart stadia via controller, so my controller definitely has no issue and it's the Chromecast having issues.
Please fix this @StadiaTeam, I have to do this way too often. Sometimes it's once a day or even multiple times a day. Despite this, it's running extremely good on my CCU. Is there any way to help fixing this?
I'm also having this exact issue. Sometimes it happens every 20-30 minutes. Most of the time it will let me hold the Stadia button to disconnect, and then hold to turn it back on. Then the controller will reconnect about 5 seconds later. As OP mentioned, the controller will still let me navigate the Stadia menu but gameplay is completely frozen (while I get slaughtered in-game for the following 30 seconds until I can reconnect). I've googled solutions more times than I can remember and nothing seems to fix it. Its certainly not my ISP or connection, and I don't know if it's Stadia software, the controller itself, or the CU.
Google/Stadia team please resolve. I'm at wit's end and it's killing my experience after I became a huge advocate of Stadia.
I would recommend for you both to contact the Stadia Support to find out if there is any troubleshooting you can do here or if the Chromecast maybe needs to be replaced.
@Shaneroc I've had similar issues, and mine seem to be related to my Nest Wifi router. I did a power-down for 5 mins on my cable modem and router, then started them up separately and disconnected. When Wifi devices had reconnected I plugged the cable back into the wifi router, and doing that let me play for ~3 hours with no issues. YMMV.
I then got a notification from Google that they had detected a problem with my router and that they wanted to replace it for free, so I'm doing that too - my wifi has always been weird but I blamed Comcast, turns out it was the wifi router all along.
Most of the time this is a connectivity issue.
Had this in the past with the default ISP modem we had.
After replacing it with a Fritzbox it is works just fine.
Other thing I did was to connect my Chromecast with a cable so no WiFi issues could cause issues.
