[Problem] Multiplayer don't working

Me and a friend are trying to play BL3 using epic games connection, but, after a long time in a loading screen, the game simply don’t work (only the host can play)… I can’t move, the HUD don’t show, it’s strange… Anyone knows how to fix it?
The map is Meridian Metropolex…

We tried to change the map, to Sanctuary, but nothing changed

A couple things:
Edit: first make sure you both are using the updated & same version of the game (three dots in Epic launcher … will show version number 1.0.6)
1: Have you tried to host & have friend connect?
2: Are you both in the same geographic area (US, Canada, UK)?
3: Go to https://speedtest.net run the test & post your stats & have your friend do the same
