CONNECTION FAILED: Unable to connect to the EA servers. Please check your internet connection and ensure that the platform client is online before trying again. For more information, please visit ea.com/unable-to-connect.
The guidance for a NETWORK DISCONNECTED case is omitted. I understand that a "NETWORK DISCONNECTED" error means that an EA server has sent a TCP/IP RST (reset) flag to my PC.
After the v1.1.3.6 update attempt, the result is v.1.1.3.5, which is indicated in the BA 6 Preference pane.
I am glad to share my experience of this issue with the community. Here is the solution that worked for me.
I figured out why the error occurred and Battlefield 6 failed to launch from the launcher session, even though I had been playing the v.1.1.3.5 game without any problems. I focused on the fact that something must have interfered with the TCP/IP connection establishment.
I looked to see what else I had changed on my desktop PC in the past few days. First, I attempted to restore the firewall threshold that I had configured strictly, one by one.
Step 1: Disable "Force Block P2P/Direct Connections" and "Force Block (P2P) Incoming Connections" in the Portmaster freeware application. No avail.
The following error message appeared:
NETWORK DISCONNECTED; Error code: 1:86001S:51001S:16054882630:21466316800.
The Portmaster indicates that connections are being initiated towards your device from the LAN or the internet. This will usually only be the case if you are running a network service or using peer-to-peer software, which takes precedence over the rules.
Step 2: Disable 'Block Secure DNS Bypassing' on the Portmaster.
# FUNCTION: Prevents apps from bypassing the Portmaster's Secure DNS resolver. If this is disabled, Portmaster may have insufficient information to correctly enforce rules and filter lists. I set this with the DNS quad 9 (9.9.9.9 paired with 149.112.112).
I finally restored Step 1 back to a strict threshold.... Battlefield 6 Launcher returns the same error code 1:86001S:51002S:57019S. Again, I put it back to disable.
Bingo! The connection is back to normal. Oops, I missed taking a lunch today.
After all, I'll have to keep Step 1 and Step 2 when I'm not playing Battlefield 6.
