Bug description

I updated to the latest stable version of the desktop client on Mac OS this morning.

After updating the dektop client to the latest version any of my uploads fail with the error message "Connection closed" and "Server is unable to maintain the header compression context for the connection".

Steps to reproduce

1. Put a new larger file into a synced folder
2. Wait for the sync process to start
3. syncing fails

Expected behavior

The files are synced.

Additional info

The desktop client logs zip file has a size of 324 MB. As the upload limit is 25 MB I only upload the actual .gz file containing a log entry related to the file mentioned above.

Do you need any other files? If so, please let me know I will add them here.

I saw this defect, but was unsure if it is the same, as the mentioned error messages from the client were different.

I downgraded to 3.13.4 which I downloaded here: https://download.nextcloud.com/desktop/releases/Mac/Installer/

Solved my problem, uploading files works fine again.

same issue.

I have this issue.

Operating system: macOS
Nextcloud server version: Nextcloud Hub 9 (30.0.0), self-hosted running on top of Docker
Nextcloud desktop app version: 3.14.0

Error messages:
"Error transferring https:// ... - server replied:" -- The visibility of this error is somehow low, as there is not enough information on both server/client sides to debug this.

Had exactly the same issue as OP, downgraded to 3.13.4 on windows and everything works.

I have the same issue....
Server is unable to maintain the header compression context for the connection

Are developers aware of this? Will a fix be released soon?

Same here on Ubuntu 22.04 with Nextcloud client 3.14.0. Nextcloud server version 29.0.7 self-installed (years ago), running in an LXD container with Ubuntu server 22.04.4.

Same problem on Windows 10 with Nextcloud client 3.14.0. https://download.nextcloud.com/desktop/releases/Windows/Nextcloud-3.13.4-x64.msi works

We have encountered the same issue in a very diverse user scenario. The Nextclouds in question run on managed servers at German provider Hetzner. After some testing we found a temporary workaround: when deactivating mod_http2 suddenly all synchronising worked again. Unfortunately I am not in the situation to figure out whether it's a problem with Hetzner's deployment or on the Nextcloud code side.

The developers are tackling the issue already: #7182

when deactivating mod_http2 suddenly all synchronising worked again.

Thanks! That worked for me too. 🙏
