I have been having the problem for a while.
1. I deleted all mods prior. (didn't change anything)
2. I tried re-installing ARMA 3 (deleted local content then re-installed). I bought the game online through steam. (didn't change anything)
3. I tried turning enabling and disabling Development Build. (didn't change anything)
4. I tried to create a new player profile. (didn't change anything)
5. Single Player works fine
6. This happens on both Development Build and with out development build
7. All multiplayer severs have a red X on the left most column, two or three have question mark. The Development severs have green dots... but are always empty.
NO IDEA WHY IT IS DOING THIS IS IT MY COMPUTER OR THE GAME? ARMA 3 worked fine with multiplayer before
