@czech1900 Have you solvled this issue? I have same problem.
I can’t access /mnt/od1 whenever the “rclone mount” running time is close to 24 hours.
Error Message
ls /mnt/od1/
ls: reading directory ‘/mnt/od1/’: Input/output error
The debug error message for rclone mount is :
rclone[5204]: /: >ReadDirAll: item=-1, err=couldn’t list files: 403 FORBIDDEN: 403 FORBIDDEN
X-Msdavext_error: 917656; Access denied. Before opening files in this location， you must first browse to the website and select the option to login automatically

rclone mount --dump headers --log-level DEBUG --allow-other od1: /mnt/od1 --syslog --rc
