Nextcloud Desktop Client don't sync files upper 10MB size

I have a Nextcloud server.
I have clients with Nextcloud Desktop Client configured.

If I add new file in Desktop Client folder upper than 10MB size, this new file don’t sync to server.
If new file is lower than 10MB size, the sync works fine.

Can you help me please?

Best regards.

There is Activity In my desktop client on Linux. There you can see three tabs - Server Activity, Sync Protocol and Not Synced. In Not Synced tab you can see the reason why file isn’t synced.

You can see Activity here:

Your cache/upload folder is not large enough, or your main hard drive, …

RadoslavCap the error when sync files upper than 10MB size is this:
server replied: Forbiddeen (Sabre\DAV\Exception\Forbidden)

tflidd: I review now your link.

Hello guys. I have the same issue. The desktop app doesn`t sync files above 10 MB.
Below you can see the report. Pushing it to GIT was not possible because it replied with a 414 Request-URI Too Large.

Steps to reproduce

  1. Install Desktop App on your computer
  2. Create a new folder
  3. Add files below and above 10MB to your local desktop folder for the cloud

Expected behaviour

All files should be synced

Actual behaviour

Files below 10MB will be synced to the cloud. Files above 10MB will not be synced

I had a similar Problem.
Is your Nextcloud Server protected throug a Firewall? Sophos WAF or something?
In my case I played arround with the firewall policy for the Web Application Firewall.
Set the settings to monitor. The sync worked for files bigger than 10 MB.
The Log file from the firewall gives you more information.

Hope that helps


Can somebody please post a working WAF config? I habe the same problem here, since updating to NC 17. In the moment I can’t find the problem. Maybe there is a problem with remote proxy configuration in Nextcloud…
I don’t know.
Download slows down to 0 and goes on error.
