File transfer broken on Android (Brave, Firefox) browsers

Trying to send a 45kB png file to XMPP client (Conversations) shows "Uploading file: ..." message with the progress bar. It then fills up until 100%, then whole message disappears, no file is sent, not even message notification is seen, nothing.

Trying to send a file from XMPP client (Conversations) to converse.js - just a aesgcm:// URL appears, no possibility to view/download.

Same behavior whether OMEMO is off or on. Text messaging works fine.

Instances tried:

• https://conversejs.org (9.1.1)
• https://conversejs.org/fullscreen.html (9.1.1)
• https://conversejs.hot-chilli.im/index-ws.html (9.1.1) (WebSockets version)
• https://conversejs.hot-chilli.im (9.1.1) (BOSH)
• https://inverse.chat (9.1.1)

Browsers tried:

• Brave Beta 1.44.68
• Firefox Beta 95.0.0-beta.1

Can you try with a different user server that's not hot-chilli?

Latest Firefox is 104, try to update that too.

[DanielKonopka]

I will try it soon. Could you please test this on your side as well?

[licaon-kter]

Using it on my own server, hosted by me, works fine.

[DanielKonopka]

Used a test account (both sides are on e2e.ee).

• I can send files from Converse to Conversations, works fine here.

• I still can't view/download files sent from Conversations to Converse, only plain aesgcm:// URL appears as message, no media is shown, even if I choose "Show media" from message's hamburger menu.

@DanielKonopka: Please set loglevel to debug and then open your browser's developer console and set logging to verbose.

Then send an encrypted file to Converse.

Check if you see any errors logged in the console.

I see now you're only using hosted versions of Converse, so you can't set the loglevel, but still, any logged errors will be visible in the browser's developer console. Please check if you see any there.
