Thanks for all of the advice! It seems the problem is only on my end, as everyone else who has tried the game has not had issues. I assume this means it is with my network connection.

What do you think the fact that it works perfectly in Incognito means? I feel like that is important to understanding the issue but I'm not well versed in coding stuff.

It is very similar to this problem:

github.com/Scirra/Construct-bugs/issues/2090

The error codes are very similar. Is there any way to fix this in Construct 3 or should I contact itch.io more? Gamejolt failed too.

I had a quick question with a game that I am trying to release on itch.io and I'm wondering if anyone has any advice. I'm running into problems when I try to export the game from Construct 3 and play it in itch.io. It works perfectly when playing it through the Construct 3 play tester.

I have downloaded the game for HTML and it is around 50 MB. Itch.io (on Chrome) displays the entire loader and loads to completion, however, the screen then goes black and the game won't start. Using the inspect element tool, I can see lots of red error messages appear in the console section. "Uncaught (in promise) TypeError: Failed to fetch" is the most common error; it occurs hundreds of times each time I try and fail to load the game. "Error loading resource: TypeError: Failed to fetch" is also very common. The number of errors seems to fluctuate each failure, for example, I had 1433 errors last time, but I've had closer to 600 as well.

Additionally:

-The game can sometimes load, start, and play properly if I repeatedly reload the page until no red errors occur.

-The game also works all of the time in an Incognito Tab. In this instance, it provides the message "Failed to register service worker". No red errors occur. I also can't save as I am using Incognito.

-On Safari the game will work all the time from what I can tell, however, memory restrictions prevent it from being a viable option as Safari auto reloads pages that take lots of memory.

-I have tried exporting the game to gamejolt which also doesn't work and many errors occur in the console tab of the inspect element tool.

I'm not very knowledgeable on this subject and I'm wondering if there are any fixes for this problem? I have multiple demos for the game available on itch.io as well, none of which have any errors despite the same export method being used. Is this a problem with itch.io or Construct? The game was originally built on Construct 2 but has always ran using the C3 runtime. Should this make a difference? Most of the demos I've released use the C3 runtime as well.

I found an older version of the game and found it still works to download a Scirra Arcade version of the game and use that in itch.io. The project loads and plays properly, and the audio even works. I could try to export that older version using the HTML option though. Do you think it could potentially reveal anything worthwhile?

Hello,

For the last 3 years I have worked on a game called "The Carnage Club". Along the way, I have released various demos for it on itch.io (https://saturnproductions.itch.io/).

All of these demos have worked despite the game growing larger and larger. It is around 209 MB if I don't deduplicate images and recompress. I found that uploading a straight HTML file didn't work with itch.io for some reason, but exporting the project for the Scirra Arcade and importing the .zip into itch.io worked.

As I am finished with "The Carnage Club", I tried to upload it to itch.io in the same manner, however, errors occur. The Construct 3 loader loads to completion, and the screen goes black. The game doesn't load any further. I have tried to reduce the file size by deduplicating and recompressing, but no further loading occurs past the Construct 3 loader going to completion. Using the inspect element tool, I found that around 1200ish errors occur while the game loads. Even the reduced file size has many errors, although not nearly as many (400ish). This doesn't happen on any of my older demos for the game. Many of these errors are "Fail to fetch c3 runtime" or "Fail to load resource".

Has anyone encountered something similar or have any advice? I've tried using Construct's normal HTML export option with no success as well.

Thanks so much,

Harrison
