Lost access to EX4100

I lost access right after my EX4100 stopped uploading and notified me that it reached 95% capacity of the logical volume. It appears offline on the cloud. What should I do?
Many thanks for your time,
Irini

@thomiren You should post this in the sub-forum for your device where users of the EX4100 can try and help you.
