Re: Cannot connect up to bf4

Ok, here are some steps you can try that can minimize the occurrence of this problems:


- Uninstall the Plugin (in control panel>uninstall) then delete the containing folder placed in: C:\Program Files (x86)\Battlelog Web Plugins


Fix for Mozilla FireFox:

- Install the latest plugin
- go to Addons (Firefox menu) -> Plugins
- Search for ESN AND Battlelog
- Set both to: always activated
- close firefox, start it again and it should be fine then


For Chrome:

-Clear Browsing Data ( Settings/Privacy )
-Reinstalling the plugin by logging to Battlelog again
-In the search bar typing the following command: chrome://plugins
-Checking the box Always allowed for ESN Sonar API and Battlelog Game Launcher
-Restarting the Browser
-Log back into Battlelog via Origin (Play from Battlefield4 icon )
-Join a Server


For Internet Explorer 11
-Restart IE 11
-From Internet Options/General tab -> Clear Browsing data -> Delete button
-From Security tab, slide the bar to bottom -> Medium Protection
-In Trusted Sites -> should be added along with and
-It will require a System Restart in order for the 7 step to be applied.

Did you update the plugin? The newest plugin was launched yesterday. There should be orange icon next to your soldier avatar at the top right of the screen.
