Netflix on a hotspot?

I’ve been having this ongoing issue now and Netflix are beyond useless about it, and I cannot get through to my phone provider’s tech support. I use my hotspot for my smart TV. Disney, Youtube and everything work perfectly fine all the time. But Netflix, works for about 10 days then it gives me an error code NW-2-5 or NW-3-6 and when I click on more details it says I am not connected to the internet, when my TV’s settings say I full well am. The only thing that has worked was to literally cancel my Netflix subscription and re activate it about a week later, but I don’t want to keep doing that. I cleared the cache, data, reset to original version, even completely factory reset my TV and it just keeps giving me the error message. I’m using an Iphone 13 for my hotspot. Does anyone have any suggestions as to what may be causing this? Netflix customer service are so useless and thick skulled about it, they are adamant it’s impossible for Netflix to run off of a hotspot, I wanted to reach through the phone and strangle whoever was on the other end!
