I'm having a similar issue. I've been through all the things listed in this thread as part of troubleshooting steps with NowTV and was eventually told I should contact Google. I contacted Google and they sent me right back to NowTV. Clearly as every other thing I've tried to cast has worked flawlessly, the issue must be with NowTV somewhere.
Some of the things I've tried:
I even went so far as to take my Chromecast with me to a friends house and hooked it up to their WiFi connection which is with a completely different provider. No luck.
Exactly the same problem for me too. I've tried everything the OP has tried to no avail.
I'm convinced (as it appears others are also) that this looks like a buggy Chromecast implementation from Sky / Now TV
I've lost count of the hours invested in trying to get to the bottom of this, and conclude that as other streaming services work without any issue , then that's where I'll be subscribing in future
Most of you chromecast users say have issues but i havent had any issues , could it be done to your hub/router and why not go onto Google Home app turn on Preview Programme to get next firmware update for chromecast because that may help.
I guess it might be worth trying the Chromecast preview programme, but I don't hold out much hope.
Having chipped away at this for nearly 18 months now, I'm sure the Chromecast firmware has been through several releases during that period of time.
After trying all this, it is still just Now TV that doesn't work properly.
Netflix, Amazon Prime, BBC iPlayer, UKTV, All 4 etc etc, all tried and work fine.
I guess the only thing left to try is another ISP. I'm with Plusnet (just for comparison with others having this issue) with a reasonable speed connection (50mb download / 15mb upload) which streams 4K from Amazon without any issues
I may try setting up a mobile hotspot network to test it. If I do, I'll report back with results
We’re experiencing a similar issue! We used to cast to a chromecast, but recently upgraded to a new Philips smart TV that we can cast to. NowTV will get as far as the loading page only when casting direct to the TV, but fails to play anything. Casting to the chromecast which is plugged in to the new TV still works however. We have no issues casting from any other sources!
Whats interesting is, we’re also on PlusNet! I think that’s now 3 or 4 people on this thread.
Would love to know a resolution!
I too have just upgraded to a Phillips TV, PUS7304(No Now TV app available on their sets according to Phillips). Now TV and Sky Store casting fails to work on the internal Chromecast. Have tried different phones, reinstalled apps, rebooted devices and router and TV to no avail just gets to loading screen then stops.
Anyone know why Phillips don't support Now TV app. Also seems strange that the Sky Store app has the same issue what with Now TV being part of that group.
Oh Sky broadband here.
@gt900uk I've just got the exact same TV and I am having the exact same problem. Did you ever resolve?
Previously been using a Chromecast which has now been deployed in another room and continues to operate with NowTV without an issue.
Like everyone else, all other streaming services (Netflix, iPlayer, YouTube, Disney+, Prime) all work without an issue.
FWIW, I'm on Shell Energy Broadband.
Actually, yes, I did solve the issue (well, my issue)
My smart home runs on a platform called Home Assistant (HASSOS / HASSIO) and it appears that this had some kind of hook into my Chromecast. It literally only affected NOWTV playback which is why it took so long to track down as I never considered this to be a potential culprit.
I noticed that when HASSOS was shut down, NowTV started to work.
Anyway, in my case, I disabled the Chromecast instance within Home Assistant. After doing this, NowTV appears to run perfectly and has continued to work for several weeks without any issue.
Hope this helps
