Xbox one - cannot connect to

I waited patiently for three weeks for the pre release beta from the 20th to 23rd to play the game on my console and keep getting the same error message “cannot connect to”.

I’ve completed my account security.
Reset my router countless times.
Reset my Xbox one countless times.
Still the same error message.
Very disappointed there isn’t more support for this issue. “It’s just in beta form, servers are buckled”. Can’t believe blizzard hasn’t figured these issues out yet.

Can anyone resolve?

I think you are a little confused … the beta ended a month ago, in August, and there has not been and will not be another beta, until the release of the game in 2 days …
