Hello, Welcome to the Forums.

See what happens if you launch Fortnite manually before clicking ‘launch session’.

I’m not sure if it’s possible to get in a situation where you’re logged into 2 different accounts - but as a way to verify you’re logged into UEFN with your username - go to Window → Output Log and search the output log for your username.

You should see a line:

LogOnlineAccount: Display: [UOnlineAccountCommon::ProcessUserLogin] Successfully logged in user. UserId=[longstringofnumbersandletters] DisplayName=[YourAccountName] EpicAccountId=[MCP:longstringofnumbersandletters] AuthTicket=[<Redacted>]

Experiencing this issue as well - however there is a workaround.
If you launch Fortnite prior to launching UEFN and then click ‘Launch session’ inside UEFN, it will send you to that session through the Fortnite window you opened previously.

Why does this happen? There seems to be some wider session validation and launching issue on Epic’s side.
