Make sure your firewall isn't blocking DCS, that you have a good internet connection, that you are on the last 1.5.8 stable version and that your integrity check for DCS is green (some mods for DCS break the integrity check)
I can see the BF server on the MP list in DCS, and can join it normally
The problem is something on your side

Thanks to answer
I tried without the firewall, I am in connection fiber (FTTH free ~300Mb/s), I am good in version 22.214.171.12423, and I tried dcs cleaner (knowing that I have never installed mods) i tried to open a port direction 10308 and i tried to disconnect my box for some hours : Nothing...
I am now away on travel , i'm on a small connection (ADSL < 3Mb/s) and the server appears in the list and I can play...
