Constant disconnecting from servers; could not find server [1]

[BigFatM240B]

Since about a week ago, every time I play the game for an hour to two, it says 'could not find server [1]' and disconnected constantly.

it always occurs during games and suddenly freezes and the battlelog message says that.

could you tell me how to fix this annoying problem?

@BigFatM240B Make sure that you added Battlefield 4 as well as the Origin client to the exception list of your firewall/antivirus software or additionally disable your protection software temporary.

Try to deactivate your firewall/antivirus software and/or check the online ports of your connection:

TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

Clear your browser cache and/or try a different browser. Reinstall your webplugins for battlelog. Get sure that you have disabled all ad and application blocking software in your browser and using the latest version of Adobe Flash.

Please let us now, if this problem after this workaround still exist.

Cheers
