EpicGameLauncher not downloading correctly

Development Getting Started & Setup
, , ,
1

I am trying to download the “Content Examples” but I am having real problems. I ran it overnight last night and it only managed 12MB whereas my network connection reported it downloaded 3GB. Nothing else was running on my PC. Also when I tried to download it today, it got so far and then stopped and even went backwards a bit. One second it reported 13.3MB and the next it was showing 13.2MB. Then it would go back to 13.3MB. Basically it would repeat this and maybe go up slightly. I had to stop it as I am on a metered internet connection. All the while it was reporting these numbers it was reporting a download speed of 30KB/s - 50KB/s. Is the latest version of the launcher bugged?

Hell AH_1001,

I’m sorry to hear that you are having trouble. I am not currently aware of any other similar download issues. Have you made any changes to your network since the last time you downloaded content through the launcher?

We have just upgraded to a faster connection but I think we have some serious problems with it. Decided to try to download a different set of assets and it did the same. Searched the logs and found a hot of errors like that listed below. I will contact our ISP tomorrow and see what they can tell me. Thanks for your response.

I am facing the same problems too. I made another topic. [BUG?]Installer percentage decreasing - Getting Started & Setup - Epic Developer Community Forums

Hi AH_1001,

Please keep us updated. What ISP are you going through?

Hi There
My ISP is a small company called Hebrides.Net. I live in a remote place and options are limited. We have just been upgraded with a 2MB connection so things are looking up.
I have an update on the problem though. I managed to download the Mixamo Animation Pack although it was difficult. When the %age started to go backwards I paused the download but in the background the game launcher continued to download data as seen by the resource monitor. After a while I started the download again and it jumped forward by 10%. However, it continued for a while and then started going backwards again. I repeated the pause and continue and it eventually completed. My network meter showed nearly three times the size of the download had actually been downloaded.
I then looked at the log files again and had the same errors as reported above but also in the ce3.log file I have loads of warnings;

“[1022/010226:WARNING:raw_channel.cc(210)] Shutting down RawChannel with write buffer nonempty”
“[1024/131913:WARNING:dns_config_service_win.cc(649)] Failed to read DnsConfig.”

Just for completeness as I forgot to state this in the original message, I am running Windows 8.1, I have downloaded UE 4.9.2 via Game Launcher but I have also downloaded, compiled and run UE 4.10 from GitHub. Thinking about it, these problems only started for me after downloading the source. I did this because I read it was a solution for the slow Intellisense in VS2013.

Hello again,

Thank you for the information. Can you please send me your debug logs and dxdiag? Instructions on how to get this information can be found here.

Hello

Sorry for the long delay, I have been away. Just trying the process again and it is still a problem, even after the latest update was applied. I am collecting log files now…

I set the debug option on and created a project based on the content examples. I let this run for a while, even after the problems occurred just to make sure I captured everything. I cancelled the download and closed the launcher, then copied the cef3.log, EpicLauncher.log and the DxDiag.txt file (uploaded). Thanks for your help with this,

Hi AH_1001,

Could you please attach the logs to your reply?

11

Hi, I’ve attached EpicLauncherLogs.zip, and it uploaded, although no visual indication while posting this that anything has happened. Have you got them now?

12

Hello again,

Unfortunately I still do not see them. Could you please e-mail accounts@unrealengine.com, reference this ticket in the body, and attach the log there? I’ll make sure to get them.

13

Hello again!

Any update? Were you able to send me the logs in?

14

Hi. I sent the file on the 11th, referenced you and the name of the support call.

Thanks.

Thank you! Attaching them now so they are in the ticket.

Hello again!

Your issue has been reported as OPP-4940.

There may be an issue with your router and the number of connections being made. Let’s modify the engine.ini file in order to reduce that.

Please locate the engine.ini file. Typically it’s located here:

C:\Users\USERNAME\AppData\Local\EpicGamesLauncher\Saved\Config\Windows\Engine.ini

At the end of the file paste in this:-

[Portal.BuildPatch]
ChunkDownloads=3

If this does not work, could you please generate a new debug log and attach it?

Changing the Engine.ini file as mentioned did indeed fix the problem, although for me the best result was to set the number of ChunkDownloads to 1.

I am glad i found this topic, Myself being in a remote place and having access to 2Mb connection, I was having the same problem than OP when downloading market assets, after 2 hours at full speed (for my connection) i would still be around the same amount than when i left, i would even see the download go backward.

Also, when i pause, it would still be downloading in the background for sometimes almost 10 min…

I just tried to put ChunkDownloads=1 and restarted the launcher and it seems to be working, will see about the long term now.
