Fix for Synology Cloud Sync: Sync folder does not exist
Synology’s Cloud Sync solution works great with Nextcloud… If it does work. I came across the following error:
The Disk Station didn’t even try to connect and every needed folder existed. Weird. After googling around I came across the following solution at Github by @mback2k:
Connect via SSH
Connect to your Disk Station via SSH. You might have to enable it in DSM under the settings:
- Open the settings
- Click on Terminal & SNMP
- Tick Enable SSH service
After that, connect to your Disk Station via SSH (use the Powershell on Windows, Linux users use a simple terminal):
Log in with the admin password and enter
sudo su – you will have to enter your password again.
Fix the SQLite database
Now, start the database editor for the Cloud Sync app database:
Clear the state for the specific problem:
UPDATE session_table SET error = 0 WHERE error = -12;
Disconnect by pressing Ctrl + D.
Restart the Cloud Sync package
Last but not least, you have to restart the Cloud Sync package. Open the package manager in DSM and click on Installed – select the Cloud Sync package and click on the arrow next to Open. Click on Stop:
Start the package by clicking on Run:
Your Cloud Sync should work again. Woo-hoo.
