Hello there,
I am sorry to see that you are experiencing issues with connectivity in general. There are a lot of reasons that could hypothetically lead to the fact that you cannot establish an online connection on BF1.
As @AlexzZz977 pointed out, a transfer of a console persona from one EA account to another is not recommended at the moment, if BF1 has been played on this account. Same goes for deletion of an EA account where a console persona is linked. There is no ETA for a resolution at the moment, but be assured that it is investigated and the team is making progress.
As for @SonoHooga, @koray140 and @SimmonsTheMad33, I would recommend contacting an EA Advisor via chat or phone since it seems your issues might be account related and therefore can not be resolved in the forums.
