You started a topic in support category.
Unfortunately you ignored the template and a lot of information to help you is missing.
Please add all necessary information like Nextcloud version, webserver type and version, os version, related log file content.
Use the support template.
Without additional information the community members cannot help you.
You probably have Nextcloud 31.0.1 installed and the desktop client 3.16.1 on Windows 11 and want to synchronize a folder with many large files.
Then the client synchronizes indefinitely and you get an error message.
Then you have no choice but to restart the desktop client and synchronize the large files one by one. In other words, delete the large files from the synchronization folder and add them again one by one.
Thanks for all the replys :- ). I just went to edit the question with the support template. Then I went into the system and just saw that I have overloaded the maximum space. I fix this, to upgrade to more space. When the problem is fixed I reply and when not I reply too, to this topic:
Hi Sanook, thanks for the reply :- ). Nextcloud has just updated his Desktop-Client Version to 3.16.2. Now the problem is fixed :- ). When it is again here, I will reply on this post. Nice regards Sebastian
