not able to login

I'm new to Linux, using fedorea.
Can you describe the start procedure in the README.md.

I've tried:
./Compiled/start.sh
The result is:
Error: Could not find or load main class launcher.Main

Operating system - Debian 9.5
When i try to login to epic games from web browser its fine but launcher at 20 percent says that credentials are invalid.
I have these dependencies installed to be safer..
nodejs npm openjdk8
Also tried that on my RHEL 7.5 machine.

The login for this (and the project it's based off) no longer appears to be working.
Not really sure where to even start when trying to debug :(

On trying to launch it gets stuck at 16%

$ ./start.sh 
Exception in thread "Thread-0" java.lang.ArrayIndexOutOfBoundsException: 1
	at launcher.EpicAPI.getCookies(EpicAPI.java:236)
	at launcher.EpicAPI.doLogin(EpicAPI.java:300)
	at launcher.LoginForm$PerformLogin.run(LoginForm.java:125)

Fails with both Open Java and Oracle Java

$ java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

I started the application, but I can not figure out how to choose a version of the engine.
Please tell me how to choose a version.

As the title suggests, the plugin downloader gets stuck at 10% (Reading chunks)

Could you please add support for two-factor-auth?

I am trying to use UE4LinuxLauncher-master but it asks for username & password in Login but it says credentials are invalid but this also happens with UE4 downloader can you please help

Suddendly it stopped to work. The Unreal Engine 4 (4.22.1) installation path is still correctly, the projects are still at the same place (and the Unreal Engine recognize them) but this UE4LinuxLauncher doesn't show it:

pretty much the same as Allar/ue4-mp-downloader#2

tl;dr: they did some changes to their api (see https://github.com/Allar/ue4-mp-downloader/pull/6/files?utf8=%E2%9C%93&diff=unified#diff-a39973b01a986e2d29455c2dd2af1c78R538 of how it would've got fixed if that project wasn't dead), which makes it require a key now.

also, unrelated, but, i've noticed when looking through the code for where it's going wrong (https://github.com/Erlandys/UE4LinuxLauncher/blob/master/src/launcher/EpicAPI.java#L914 btw), you're kinda faking to be that project in your user agent, maybe that might wanna get a fix too? ;)

Hi. I'm facing trouble that marketplace is empty. Maybe it is somehow related with messages in the terminal:

UE4LinuxLauncher/Compiled$ ./start.sh
java.net.MalformedURLException: no protocol: /marketplace/en-US/
org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]

This fork of ue4-mp-downloader could be used as reference:
https://github.com/seesemichaelj/ue4-mp-downloader

I forked this as the original version didn't work for me. It used what looked like an older authentication handshake that used unrealengine.com instead of epicgames.com auth. This repo also adds support for 2FA!

I might make an PR, but its low priority for me atm so don't wait for it.

leaving this as suggestion to solve the login issues

That was displayed on the button of window. Is current login auth out-of-date?

As per subject, the file that EpicApi.java uses to select the engine version is not longer at /Engine/Binaries/Linux/UE4Editor.version but inside another directory.

A work around is to create a symlink inside /Engine/Binaries/Linux/

cd Engine/Binaries/Linux/
ln -s Binaries/Linux/UE4Editor.version 

Can not login using default usename password and without 2 Factor Auth. the error is 1008

with 2 Factor Auth, doesn't work either

it shows java.lang.NullPointerException in background terimnal

Im using Debian 9
Im try as root but not nothing.

Many of my assets will not download. It freezes at downloading manifest.

I noticed that the Unreal password is saved as plain text.

When I try to log in I am seeing this. There is no info in the terminal. I log in using my email address and password as on the web login. If I use my username and password, it gives me invalid credentials.

When I type in my two-factor auth code and hit Confirm I got freeze and an "java.lang.NullPointerException" in terminal.

I'm trying to follow the instructions how to pass the Captcha BDA test, but when I open the page from the browser there's no captcha requested, so there's no data to copy. Tried deleting cookies, incognito window, but no luck.
