Tech question - returning error message???

[BCH]

Help Please, I have just recently been receiving continuous error messages when I try and make any moves: Deploy, Attack, Fortify etc...
The Error message is always the same & I need to refresh anywhere between 1-6+ times!
Message I get reads: "Error with the request: status code is 12019"

Any help to get this to stop would be HUGELY appreciated!
Thanks!

That doesn't look like a CC error code.

Are you using FF, IE, any greasemonkey scripts or plugins?
