Hello there @Antaras9!
Checking through your log, the main issue should come from the following line:
OpenSSL SSL_connect: Connection was reset in connection to api.epicgames.dev:443
This error is tied to HTTPS comms, so something is indeed blocking your link between Epic and your main rig. From other cases across the community, the usual suspects are your antivirus, your firewall, and any active VPNs:
-
From your security (antivirus and/or firewall), add exceptions for UnrealEditor.exe, EpicGamesLauncher.exe, and UnrealCEFSubProcess.exe, then disable any functions related to SSL scanning or HTTPS inspection.
-
Make sure port 443 is not being blocked in your firewall. As a last resort, disable your antivirus.
-
If you are working with any VPN, disable it for testing.
-
Perform a flush DNS and network reset, and restart your PC afterwards:
ipconfig /flushdns
netsh winsock reset
netsh int ip reset
-
Please get the latest Windows Update for your system, so your root certificates are updated as well.
-
Navigate to EpicGamesLauncher\Saved\webcache and delete any webcache folders present there. Open the Launcher again after that.
-
Last resort, a full uninstall/reinstall of all Epic software:
- First, uninstall the engine, launcher, asset packs, etc
- Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
- Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
- After that, no elements related to UE should be left in your system
- Now, reinstall UE launcher from scratch, and only add the latest version of the engine
- After the process is complete, open the launcher again
