Misc Error 23400 on COD

[giacomo1978]

hello everyone, I would like to understand why every time I try to access "online" to the Call of duty I always get this error "23400"
Yet until a few months ago I connected without problems ..
Has something changed?
What should I do to make these COD games work again?

Two weeks ago you were able to bypass error 23400 with some gecko codes that @leseratte linked to. Unfortunately these no longer seem to help and I'm guessing it's because Activision have shut down the servers.

hi, they all work, except COD MW3 I get this error: unable to connect to call of duty servers MW3 please try again later.
what can I do? the other two work,does COD MW3 work for you?

My PAL copies of MW3, MW Reflex and Black Ops currently say "Unable to connect to the Call of Duty: <game> servers. Please try again later". They were all working last week.
