Hello.

I have a problem with my Chromecast Ultra, where I am unable to complete the installation totally. A message appears at the end of the Google Home app setup that says to check if my phone and my Chromecast are on the same network. I try to validate the setting by opening Google Home and clicking on the Chromecast icon, it opens, but unfortunately it says it is "unavailable". My phone is a Samsung Galaxy S20 Ultra 5G and my Google Home app is up to date. I have been using Chromecast Ultra for 2 years here in Brazil and it has always worked correctly. I have switched to TP-Link Deco M5 for 2 months and did not have any problens until yesterday. The only change I made to the router recently was to hide my SSID, and since thet change everything started to go wrong. I tried to reverse the procedure, but it didn't work. I have already restored the factory defaults for Chromecast several times and my router. I also removed all my devices on Google Home, but I was unsuccessful. What else should I do? Has anyone got the error I mentioned at the beginning? Sorry for the text size and I thank anyone who can help.
