Let me explain and hoping, may be Vodafone pro tech guy can help me. I see this situation as "Man in the middle". Long story shot: Netflix error code is 251-251. What had been done:
no VPN, no DNS proxy
reboot modem a few times
reboot router a few times
called Netflix with this error, 30min spent, no help, said the problem with other end
called Vodafone, saying Netflix wont help, nothing from Vodafone.
Devices used: Nvidia Shield TV, Apple TV, Vodafone TV - same story.
Internet works fine, no problem at all, I can watch Apple TV+, Sky Sport Now, all NZ TV channels, etc.
changed DNS from Vodafone to Google - nothing changed, same error
Am I right saying that somewhere something cached between Vodafone and Netflix? And How long to wait to clear cache?
