What is the problem you are having with rclone?
Usually to mount a single cloud service I use
rclone mount Mega1: x:
I know that it is possible to add the --network-mode parameter, the usefulness of which I have not grasped, however: as far as I have seen it merely makes it more difficult to unmount the cloud.
I don't think it has anything to do with today's problem, but when I researched how to mount cloud I read about this parameter.
However, I have registered in RClone many clouds, and the letters of the alphabet are limited. 
How can I mount multiple services under the same letter?
