An undefined error occured

I'm having the same issue. Any luck?

Same issue here and it’s we going for 2 days never heard of such an ongoing issue in a game 

I am not sure if thats the actual reason. I had another error message (I can't remember exactly what it said) but that made sense to be caused by not having available servers. I now get the same error as described here (undefined error) and that even at times during the day where I had no problems in the last days. So I actually don't think it is due to them not having any available servers.

I could fix the problem. I had this message only when I wanted to host an experience. I just republished the experience in the portal and that fixed the issue. Just in case someone is experiencing the same.

I have not been able to play battlefield six for 2 months now because of this error and I’m thinking the game was a waste of money

2 months here
