An error occured while opening a folder Operation canceled

#1

Hello,

I am new to nextcloud, that I want to use to synchronize my files over a couple of computers.
My server is running on a RPI3 (using the NextCloudPi docker image) and it uses an external local storage (that is actually a NTFS disk mounted on the RPI and in the docker).

On one computer I was able to synchronize all my files without any issue (using the Windows Client), which make me think that the server is working just fine.
But on another computer I have one folder that keeps failing with the same error. I tried both the windows and the linux desktop client on this computer and both are failing with the same error:
An error occured while opening a folder Operation canceled

Do you have any hint on what could be the issue ?

Thanks in advance,
Loic

@ Loic_Quertenmont Any luck finding solution?

I have same here. Wonder if there is any limitation on file number for desktop client.
In my case over half a million files. Seen nothing but RED ERROR lines from nextcloud
