It says “connection to server failed”. I recently switched browsers, but that must be a coincidence.Any direction could help.

Hello LostScout,

If you can right click on your Epic Games Launcher icon and choose " Properties . " From three navigate to the Shortcut Tab. You will see a section labeled " Target. " If you enter -http=wininet to the end does this fix the issue. This is a fix for windows only.

Here is also a link to Troubleshooting with the launcher :

,

I added the -http=wininet and now I am getting a new message that says “could not establish a web session. please try again”. My connection seems good and my credentials are accurate.

At least I got a different result. Anyway, thanks for the response. I will keep you updated if a solution is found. In the meantime, any additional direction would be much appreciated.  
Thanks again!

Also, the launcher began to crash. I went back and deleted the -http=wininet and that seemed to fix the launcher crash. However, it now says"connection to server failed" again.

This problem persists with the unity Launcher as well. I am not behind a proxy server and I do do not see any potential firewalls that could be causing the problem. I am getting desperate. Any luck on the situation?

Don’t laugh, but try the google dns servers. My Windows Store would not work without… I know, odd. but…

The Google Public DNS IP addresses (IPv4) are as follows:

8.8.8.8  
8.8.4.4

I changed both IPv4 and IPv6 DNS addresses to Google`s DNS servers. The problem still presists…☹

I have noticed that when I do not have -http=wininet included and go offline, that nothing in the editor is connecting, however when I do have -http=wininet and go offline, the news section of the editor is connected to the internet…but that`s it.

It is like things are partially connected.interesting.

Hi LostScout,

Could you please provide your launcher logs and dxdiag? Steps on how to get this information can be found [here](https://wiki.unrealengine.com/Troubleshooting_Launcher_Problems#None_of_the_Above_Helped_-_Getting_Debug_Logs).

Also, could you provide two sets of launcher logs. One with " -http=wininet" included in your target line and one without.

Thank you!

Another observation I made is that when I hit sign in with out -http=wininet added, It automatically says connection to the server failed…regardless of the password I enter. However, when I add -http=wininet, entering my password will result in the message “could not establish a web session. please try again”. Although, if I enter an incorrect password, it checks my credentials for accuracy.

Hi Lost,

Can you take a screenshot of your current proxy settings?

You can see these by going to:

Control Panel- → Network and Internet → Internet Options  
Select the Connections tab then click LAN settings at the bottom on the window.

Thanks!
