Chromecast won’t communicate

[Mikeysheff1]

My chrome cast has worked flawlessly the past couple years. I moved into college and i opened the google home app to find my device and it isn’t there so I looked at “chromecast.com/help” and it told me to reset my device. So I did, I reset it and I tried to setup the chrome cast as a new device and I ran into a wall. Now mind that the wifi at my college works amazing, it’s fast with strong connection despite how many other students using it. After I tried to connect it to wifi, my tv currently says “Ready to cast” but on my iPhone, it was still trying to connect, after a couple minutes and it finally said “connected” a couple second after that, it said “Dorm TV may be set up, but we could not communicate with it from your iPhone. Make sure that you have enabled local network access in your privacy settings and try again.” I looked in my settings and saw that my local network access was enabled. I’ve tried connecting it with two different iPhones and it does this same thing over and over. I’m stuck and I’m not sure what to do.

I have also reset my iPhone as well, both of them to eliminate if that was the problem.

Your school probably has device isolation turned on. Contact the IT department.

I brought my tv from home, would device isolation still fall into this category considering it isn’t wired into the wifi and both are wireless

Device isolation keeps devices on the same wifi network from talking to each other. When you first add a Home device it talks directly to the phone. Then the phone shares the wifi info with the device. Once the device is connected to the network it is isolated from other peers on the network. There is a device called a travel router that would acts as a wifi hotspot that connects to your school wifi. But, some schools don't allow them.

I’ll get in contact with my it department tomorrow morning and I’ll try the travel router as soon as I can get my hands on mine at home. Thank you.

I have same problem with my Gen 1 which was working well past years. Now I move to new house and new Wifi, and try to setup it after factory reset. The LED light shows white blinking, but Google Home cannot recognize it.

I also setup a Gen 2 and it’s working well.

Can you please help?

Hey, I found this link helpful, and I can connect my Gen 1 now 

Hi bud, this link explains what to do. For those still using 1st Gen Chromecast and getting a 'No Device Found' error, I managed to find so...

Read the main paragraph and you can set up your Chromecast once more.
