Hi Jodamsu,
We’re very sorry that you are having these troubles. We are still investigating the cause of this for the few users who experience this problem. We may be in touch for additional information.
In the meantime, while the Launcher is not cooperating, you my wish to consider using the source code version of the editor which is downloaded via GitHub. It is a more involved setup process, but it can probably get you started. More information is available here: - YouTube
Thanks.
Hi There, I just started the engine and I receive the same problems. If you want I can give you team viewer acces and you can test on my PC. just let me know.
Same here… before I was getting the version error, now I get the 2nd error as well asking if I’m connected to the internet. Well… I’m fairly certain I am. Unless this post made its way online through sheer force of will.
@Wobbleyheadedbob and @Ion Cocarcea,
Very sorry to hear that you are experiencing this issue as well. You have tried restarting the Launcher, and the problem still persists?
No proxy? Firewall disabled? And you have tried disabling your antivirus software?

Thank you
I tried the solution and nothing was working but I managed to use it in offline mode. Fired it up again later the next evening and all was fine, the launcher seems to have updated now.
No problems since then.
(PS: Thanks for responding!)
I started the launcher in the next day and all is fine after update.
Awesome! There must have been some network hiccup, but I am glad it did not last long for either of you.
Cheers!
I’m getting the same thing in my logs: HTTP/1.1 503 Service Unavailable: Back-end server is at capacity
Also, same as you, none of the suggestions work.
Same as ECXevian: HTTP/1.1 503 Service Unavailable: Back-end server is at capacity
None of the suggestions work, even DNS change…
Need back up here, i bought Engine today 
UPDATE: it started working just of now! N-I-C-E-!
Just pinging the staff in hopes that will get this issue solved as quickly as possible.
The Launcher error comes because of 503: Service unavailable on servers end. See below for recent comments.
Please get this fixed! Subscribed today for the first time, this is really not a good way to impress new customers, hehe.
Having my hopes high for quick resolve! Cheers!
Also just confirmed identical error on Mac so it’s not platform based.
same here since today.
Suddenly it just moved on, and now it’s installing Hope that’s it!
The issue seems to be resolved. I am assuming it was a server problem? If it was, then @Unreal dev team. Could we please have some better error messages for when the servers are down?
