The issue you are facing:
I’m currently trying to sync some files from my computer to my nextcloud server, and there are some errors during the sync, making it impossible to upload the files.
The issue is, there is no error in the nextcloud client (screenshot), it just says “Server replied : (ignored due to previous error, new try in 24 hours)”
There is nothing in the nextcloud server logs or the apache server logs. I really don’t understand the issue.
I have a nginx reverse proxy which redirect to another server with an apache webserver and nextcloud.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Configure Nextcloud client
- Send files
- ???
- Errors
