I get this error message when trying to connect in battle.net:

Common Problems
Could not log in to Blizzard services.
Error Code: BLZBNTBNA00000A8D

Things I have tried:

-restarting modem, flush dns, release/renew ip
-trying another network (mobile network iphone)
-restarting pc several times
-allow battle.net through firewall
-delete battle.net patch folder, reinstall patch
-delete battle.net, reinstall battle.net
-try logging in to other regions
-check for network driver updates (ethernet was updated, installed apple and network drivers to share from iphone)
-closed all non-essential programs

None of the above attempts solved my problem.

I have no other issues with other things on my desktop.

I can only log in to battle.net in offline mode. I downloaded Diablo II Resurrected, but am only able to play the intro video.
My neighbour could easily log in, and is currently playing, no problems :S

Do anyone have any ideas that can help me fix this issue? Thanks!

Additional information, both for those who can help me, or others experiencing similar problems:

I installed battle.net on another computer (laptop), and it is the exact same problem there.

So it doesn't seem to be system related (same problem on two different devices) or networks related (same problem on two different networks/ISP, fibernet provider and mobile 4G).

My neighbour can log in fine, so is it then an issue related to my account?

Also error code is: BLZBNTBNA00000A8D (1310), didn't see the 1310 at first. No google search provides this error code with 1310. Moreover, no search on battle.net forum provides any result for just "1310".

It's wide spread server issues some people are lucky others are not

Get fkt kid
We in a2 now

"Blzbntbna00000a8d" thats the sound i make as well out of frusteration

Nice representation of the internet here, I had to crack a smile!

We have the Lawful Good @Munchie, who tries to help the situation however he can, the Chaotic Evil @Ambient444 the "get rkt kid", and the Chaotic Good @Unbornsav who tries to bring a smile to my crying face!

Although I don't see anyone else having issues the same as mine. I see people logging in, but unable to play the game, or getting kicked out of the game etc.

After trying a bunch of things, I finally managed to solve the issue.

I am not sure why it was like this, but while trying to reset my password from inside the web app, I got the error message "incorrect password" (even though it was the correct password, that both web app and desktop app recognized).
I then logged out of the web app, and did a password reset using this link: https://account.battle.net/recovery/en/identify-account.html?requestType=PASSWORD_RESET

After doing this, I could log in as normal into battlenet.

Doubting that anyone else reading this has this problem at this time, but if you do, just do the above!
