Just tried to switch characters after a doubles match and now I am unable to login, I keep getting the same error that I have lost connection to the Destiny 2 servers and that my permissions to access online multiplayer gameplay may have changed or my profile was signed in elsewhere. Edit: was able to log back in after resetting my router.
This can usually be fixed (on console) by clearing the cache. It has always worked on XB for me if I get the error, but is sometimes more involved on PS for some reason. - unplug power for 10 minutes - ([i]power cycle the router while you are waiting[/i]) see if it works properly afterwards
