Server stopped accepting new streams before this stream was established?

[TheUnexpectedGuest]

Hi,
I’m running nextcloud on an external server hosted by HETZNER. I use windows with all folders and files synced via nextcloud client. Now I have an macbook and wanted to sync my nextcloud files on an external usb drive in my macbook. The drive has 2TB, on my nextcloud server I have around 600GB.

When synchronising I’m getting the error “server stopped accepting new streams before this stream was established”. I have formated the external drive as ext-fat as well as macios - for both the same.

What is this error about? Client and server has current NC version.

Thanks, Rainer

Same on Appimage v3.14.0, client won’t sync and throws this error.

I was also looking to see if it was reported on GitHub and it was: Sync error: “Server stopped accepting new streams before this stream was established” · Issue #7136 · nextcloud/desktop · GitHub Looks like the client has had http2 re-enabled which seems likely to be the cause. The quick workaround, if you’re in control of your own Nextcloud server, would be to disable http2 at the web server level for Nextcloud.

It started with the new version (3.14) of nextcloud app, so I stepped back one version (3.13.4) and let me see …

I can attest that 3.13.4 does not have the issue in question. I went ahead and downloaded that version (just replace the version number in the URL for the MSI installer in my case) and exited the existing client, installed on top (skipping any restart process or computer), and it worked flawlessly on launch. Flying through file transfers.

Seems a buggy HTTP/2 implementation to time out and then try flooding again instead of backing itself off in rate, or downgrading.
