Very frustrating. Seems that HULU and fire stick have issues. No problem when using Samsung smart tv. But tv's using fire stick and hulu are problematic. About 15 minutes into watching the hulu stream freezes. Only way to get it back up is to reload Hulu or force stop hulu and go back. Very time consuming and frustrating.
I have the same problem too. I chatted with Hulu and they reset it, but said it was a Firestick issue so to contact Amazon. I have to restart my Firestick every time just to get Hulu to load. Netflix will load fine. The only thing that I haven't done is see if there was an update. I guess that will be my next step. It gets annoying to have to restart it every time I turn the TV on.
I too have been having a load of trouble with the HULU app on both of my Fire TV 4K sticks. None of the other apps are giving a stitch of trouble. The HULU app averages 7 out of 10 times of not starting. When I start the app the screen will go black and just stop loading with no response. To get it working I have to go to the home screen, settings, manage and do a restart iof the fire TV once the restart is completed the HULU app will work. However having to restart the Fire TV almost every time we turn on the TV is becoming quite annoying and a time waster. I certainly hope Amazon will figure this out before I have to go to another brand of stick.
Same thing happens to me every damn time!!! Beyond frustrating to have to restart the app all the time. Then when i get it back to working it starts the show about 10 minutes backwards so i have to take the chance of fast forwarding hoping it doesn't freeze again
Firestick purchase about 2 months ago - constant issues with Hulu locking up. Firestick is updated, All applications are updated, firestick is wired into network, Spectrum modem is updated, download speedtest shows 100MB+ consistently. The only thing that helps on a temporary basis is a complete power cycle of the firestick but locks up again after about 20-30 minutes.
