I just checked permissions, I don’t know if it’s good, I’m a beginner Linux user
So thank you, I’ll try to ask the seedbox forum if I can’t resolve the issue
Update : I tried to set /syncthing as path (volume point to /srv/dev-disk-by-label-Files/Syncthing on Docker/Portainer). This is not the same error :
2020-07-02 00:57:15: Failed to create folder marker: mkdir /syncthing/.stfolder: no such file or directory
2020-07-02 00:57:15: Error on folder “Radarr” (vkgsd-h2ftm): folder marker missing (this indicates potential data loss, search docs/forum to get information about how to proceed)
