Can't upload files larger than 2GB

[LPLDevs]

Hi,

We are trying to create a website to transfer and share files up-to 15gb. We're using jDownloads to process and manage the uploads/downloads.

We know in order to allow large files to be uploaded we know we need to alter the PHP.ini settings, so we've increased the settings to as follows...

- UPLOAD_MAX_FILESIZE = 80000M
- POST_MAX_SIZE = 120000M
- MAX_EXECUTION_TIME = 1800
- MAX_INPUT_TIME = -1
- MEMORY_LIMIT = 12800M

As you can see in the following screenshot, everything appears to be configured correctly in the PHP.ini settings to allow larger uploads - https://prnt.sc/pgwzmc

We've also set the chunk size in jDownloads to 200mb chunks. But we're still not having any joy... We can upload ZIP file at 1.99GB successfully, but we can't seem to get above 2GB! It just returns with "ERR_HTTP2_PROTOCOL_ERROR"

We know browser upload on big files historically are hard, but we're using Chrome which exceeds 2GB limit.

So as far as we can see all should be fine? Are we missing something?

Please advise.

Many thanks in advance.

We've also tried using "All runtimes", letting jDownloads/browser choose the most appropriate runtime, but still no Joy

Here's a screenshot of our upload settings, in case it's any help - https://prnt.sc/pgxlf3

Hi
Not sure about this but it maybe browser specific.  Seems Firefox might be OK but Google Chrome is apparently problematic see https://stackoverflow.com/questions/58215104/whats-the-neterr-http2-protocol-error-about
Another possibility is that your server maybe using a 32bit PHP

You should at first contact your hoster. I think not that this is really a jDownloads issue.
