I'm working on an iOS sender app for Chromecast. I have two Chromecast devices set up and was able to detect and connect to both of them until I switched to a different test iPhone, and now when I try to scan for Chromecast devices, the deviceDidComeOnline message is never sent.

I am able to reproduce the problem with the sample app here, with version 2.5.1 of the GoogleCast framework. The following is console output from the sample app when it fails to detect a Chromecast:

This is happening on an iPhone 6+ running iOS 8.0. When I open other Chromecast compatible apps (Chromecast, YouTube) on this phone, both Chromecast devices are detected successfully. It's just the apps I run from Xcode, and just on this particular test phone, that seem to have this problem.

I've tried the same sample app on several other test devices to see if it had anything to do with the device / OS. Both Chromecast devices are detected without issue on the following iPhones/iPads:

  • iPhone 6 on iOS 8.1.2
  • iPhone 5 on iOS 8.1.2
  • iPhone 6+ on iOS 8.0.2
  • iPhone 5 on iOS 8.0
  • iPad Air on iOS 8.0

Any idea what would cause this? Thanks in advance.

Reset to default

It is Possible that the certificate problem was caused by an invalid date on the phone. Check the date time is correct because this could cause the certificate issue and then the Chromecast Issue

Apparently the iPhone I was using had a certificate problem.

Going to Settings->General->Reset->Reset All Settings fixed the problem. At first I tried Reset Network Settings, but that didn't seem to help. Not sure if maybe the combination of both is what did it.

I experienced this when the time and time on the device was incorrect.

When I corrected the date it worked as expected.
