BT sport casting to Chromecast ultra in 4K

[saltsupplier]

I have recently gone over to full fibre.

I used to be able to cast from the sport app to chromecast ultra in 4K but on occasions it buffered hence a good reason to go over to full fibre.

I can no longer cast in 4K to chromecast ultra it instead reverts to BT Sport 1 instead of ultimate.

I did manage to get it to work for approx 5 minutes after rebooting the hub.

There is sometimes a fault code CC_S6001 but I cannot find a record of a code online.

I have contacted Google and they say it is an app problem not them.

Prime and Netflix work fine in 4K.

Search through the forums as I think this question has been discussed before and it's something to do with certain versions of Chromecast and the BT Sport app security protocols If I recall

I thought the S6001 issue was fixed now - I'll check logs tomorrow.
We do sometimes see Chromecast devices reporting that they don't support 4k if they're turned on before the TV - rebooting the Chromecast with the TV left turned on and switched to the correct input should fix that.

Also worth mentioning, just in case - not all events are on BT Sport Ultimate. Was it specifically an Ultimate event where it showed you BT Sport 1 instead?

The chromecast ultra is in a cinema room.

It was ultimate live broadcasts of rugby.

I can send you a video of what has been happening.

Don't see if I can through the community but if I can let me know how or send an email address.

No video needed, thanks.

I'll check our logs tomorrow. If you could send me a DM with the BT ID you're logged into the app with, that'll help me check your specific scenario.

Sorry new to this!

How do I send you a direct message through the community?

Is it just through reply?

Thanks for the report @saltsupplier - you're right, this error is back.
We had a temporary fix in place, but it was removed so that Google could help us with a proper fix - we forgot to put it back before the next live match.
The temporary fix has been put in place again, so you shouldn't see CC_S6001 again.

When CC_S6001 is triggered, it automatically switches to BT Sport 1, so that explains the other issue you mentioned.

Sorry for the inconvenience.

Thanks Darren.

I can't unfortunately test it until next Friday as I am away and I think the next ultimate broadcast is tomorrow.
