I am having some trouble to connect the netflix app from my android app to a chromecast. Briefly, it takes a long time (from 5 to 30 minutes) until the cast icon appears in my netflix android app as if chromecast was not announcing itself on the network. All devices are connected to the same WiFi network running on Ubiquiti/Unifi hardware.
I tried resetting the network, the chromecast, enabling Multicast DNS without success.
I am not sure where the problem is as the weekend that this started there was (1) an update for chromecast, (2) an update for all the devices in my network and (3) I changed my ISP. Before this problem, the casting icon was appearing a few seconds after it was turned on.
In addition, the Google Home app in my phone seems to be finding the chromecast way before. Any ideas who to solve it?
