Firestick not working

My firestick 3 just stopped working. Tried disconnecting for 30 seconds and reconnect, I get the main screen but cannot navigate. Put new batteries in the remote, still cannot navigate. Does anyone know if the problem is the remote or the stick?
Thank you

Hello @glachance474 you may need to pair the remote again. Sounds like your remote to me. You can also install Fire TV app remote on your phone and try that. See this - Firestick Remote Not Working? - How To Fix, Pair, and Much More
