Unable to upload file to community [solved]

I just tried uploading a hex file (and also a zip file) to the forum. But after it’s uploaded an Upload error is reported and the file is not added to the post.

Anyone having same issue?

Edit: It seems to fail in Firefox. Chorme works fine.

It would seem not:

Minesweeper.EN-GB.hex (59.5 KB)

(I am on Firefox.)

Worked fine for me. Firefox under Ubuntu Linux.

HelloWorld.hex (17.8 KB)

Does it work after restarting the browser? Perhaps clearing the cache?

Thanks @Pharap @MLXXXp for testing.

Yep I tried that and some other things before I made the post. Odd thing is I tried today the same on my Windows laptop @ work using Firefox (latest version) and get the same error.

Any chance you’ve got like an ad-blocking router or something like that?

Might be one for the discourse forum but so far it seems to be an isolated incident?

Solved my problem.

I have the clearURLs addon installed that even caused problem when filtering was disabled. A workaround is to disable the add-on from the add-on list for an upload and re-enable it afterwards.

It’s still odd though as the problem only occurs on the Arduboy community and not other similar discord communities.


I’m hosted on discord so I wonder if it’s their host that’s doing it, other people might have their own deployments.

I don’t know if the google api maybe the other sites aren’t using it?

Looks like the difference is that Arduboy community uses AWS/Uppi/Javascript which uses ETag headers and the other site used plain old html post method.

I’m betting it’s hosted on Discourse, not Discord.

Sold bet.

My guess is yeah they are probably deploying it on their own server which uses this method, and it’s free to do so. I’m paying a monthly hosting fee.
