Unable to log into UEFN


Summary

I am completely unable to login into UEFN. Every time I attempt to open UEFN I am shown an error tab which reads
“Login failed: Unable to login to your Epic Games account at this time. Please try again later. UEFN requires a successful login to run. Shutting down”. Sometimes UEFN will open
an Epic games account verification tab (https://www.epicgames.com/id/activate/ 1) on my web browser with the option to connect my epic games account to UEFN. Every time I click “allow” UEFN will still not be able to log in.
I have tried many different ways to fix this issue such as uninstalling UEFN and verifying the game files however none of these methods seems to work. This issue first occurred on the last days of 30.40 update and I am still having this issue even after the 31.00 update.

Hi This was a common problem

Windows 11 needs to Run As Administrator to install UEFN updates

Works fine on Windows 10, but Windows 11 Enhanced Security needs “Run As Administrator”

There may problem may be running Opera.
Try Microsoft Edge and Google Chrome to initially log in and join your Epic account with Fortnite and installation then you can go back to Opera but we have seen problems where VPN had to be used with browsers other than Chrome and derivatives.

UPDATE - 23-jan25 loaded Opera on Win 11 and tried as you described.
So here are the features that are different from Google Chrome

Free VPN: Protects your privacy by securing your internet traffic

Epic does NOT support configured VPN by Opera you must conform to Epic internet settings.
Win11 will NOT allow Opera to configure the Windows firewall and does not recognise the cached cookie and your firewall.
Unreal Engine must have Chrome on Explorer and you MUST set Chrome as your default browser to allow login to Epic UEFN servers installation.

You need to find Opera setup manual and manually configure the VPN, EPIC does not support

Built-in ad blocker: Blocks ads and popups, which can improve page loading times and protect against malvertising

The authentication page is a popup and Opera is blocking this

Protection against trackers: Protects against tracking scripts on websites

Well login is a website script so that’s blocked EPIC as well.

In Summary only Google Chrome must be your default browser of MS Edge ( based on Chrome)

The Client Windows firewall is not correctly set up.

The problem lies with your PC not being configured to support EPGL and hence Fortnite

Its not a bug its client PC incorrectly set up

ive had this problem for over a year now, i just have to run it over and over, takes a few hours but sometimes it opens. ive lost a lot of money and entire clients due to this error. any fix?

hi @BazooStudios ,
As in my previous post use Google Chrome as the default browser and Run as Administrator when installing and using Epic Games Launcher.
