BF1 failed to connect to EA Online

I bought two games from Steam, Battlefield 1 and Battlefield 5. While BFV runs smoothly for me and I've already played 13 hours, BF1 brutally rejects me, saying it failed to connect to EA Online.

What I tried to do:
- Restart PC
- Restart the internet
- Add EA and BF1 to antivirus and firewall exceptions
- Disable antivirus and firewall
- Wait 24 hours

It's still not working. Not that I hate the BFV, but still.
