Wallpaper Engine upload error (Steam internal error) [Solved]

[Death Rex]

Hi there, I just got an error message when I tried to upload a scene wallpaper I made. This is the error message: https://i.gyazo.com/ebadec38657ae07c471f947e7030b497.png
It's in German, but maybe some people recognize the format of the error.

I tried the basic stuff:
- Checking if other people have this issue too
- Tried uploading a different wallpaper
- Restart Wallpaper Engine
- Restart Steam
- Restart both individually, open them individually
- Restart PC
- Deleted the temp folder, in case it's a read only error
- Run a check-up on wallpaper in case some data is faulty

I'm now on my wits end and was wondering if somebody had this error as well and could help me out, thanks!

Are you using any sort of antivirus app or firewall (except Windows Defender)? Usually this is caused by something like that but unfortunately this error is the most generic. It could also be a server-side error, I actually see that you have uploaded to broken Workshop items. Maybe wait an hour and try again later.

I forgot to mentioned that I already tried turning off the firewall and I'm not using an antivirus software currently. Then I'll take your advice and try to wait more, I'm keeping you updated.

What firewall solution are you using?

[Death Rex]

Just Windows Defender

Are you able to upload Workshop content for any other games? It looks like you have some Portal 2 Workshop items so perhaps you could try making another Portal 2 item and see if that still works.

Does it show any specific percentage or does it show this error message immediately?

It does work for Portal 2, no problems here. The error message always appears at 45%

Steam starts its upload process at 45%, I am not sure why it would work for Portal 2 and not Wallpaper Engine. Could you share the log file from our scan tool by sending it to [e-mail]:

I just send the email

Unfortunately I don't really see anything that should cause this to happen, this is pretty unusual. Can you try and reinstall Wallpaper Engine entirely? It looks like you have been using the app for years, so maybe something in the last few months broke some aspect of your wallpaper_engine or Steam installation.

Make a backup of your config.json and and the wallpaper_engine\projects\myprojects directory. After uninstalling the app, manually delete the remaining wallpaper_engine directory. Then reinstall the app and place your old config.json and projects\myprojects directory back into the folder to get your project and config file back.

Then try uploading your project again.

Just finished the reinstallation of Wallpaper Engine like you said, but I got the same error... I'm clueless as to what it is exactly, but I'll try uploading the wallpaper from a different PC to see if anything changes or if it is a network problem on my end

[Biohazard]

Is there anything special about the installation path of Wallpaper Engine perhaps? I.e. what I mean is whether you may be using symlinks or network shares or anything out of the ordinary for your Steam library on E:/.

Like Tim said, this kind of issue at 45% progress is typically that Steam itself cannot communicate with the relevant Steam servers but this tends to affect all Workshop games and is simply due to some IP/port restrictions either in the router or a firewall software.

But at this point it looks like your issue is different from the ones we usually see.

Also, please try reproducing the error once more and then immediately close Wallpaper Engine and Steam. Then create a zip file with all of Steam's logs that you can find here: C:\Program Files (x86)\Steam\logs and send us this file to [e-mail] as well. These might contain some clue about the issue from Steam's end so I think it might be worth a shot.

[Death Rex]

Nothing unusual about the installation, I didn't change anything specifically for wallpaper engine.
I'll follow your instructions tomorrow after work and send the email, hopefully we'll get closer to the solution through that

[Death Rex]

Just send the email with the log files

[Tim]

I am afraid the log file just shows that Steam's server connection timed out when it attempted to upload content to the Steam servers. Again, this looks like a network issue. I have no explanation for why this would not happen with Portal 2 but maybe they have some sort of hard-coded different server or port in Steam - your Portal 2 upload is actually not in the logs at all so I assume Valve does something special there for their own game.

The only suggestion I could make at this point is to use USB tethering or a wifi hotspot with your wallpaper and try that to upload your wallpaper. Maybe your network router is for some reason blocking the upload. If the problem persists even when using your smartphone's mobile network, then it's likely some issue on your computer directly.

[Death Rex]

I was able to upload the wallpaper from a different PC in another network router (but same account). This doesn't resolve this issue, but it confirms your statement about the blocking part
