MCH appear offline in Android app

The MCH may be busy doing indexing or uploading to cloud (if enabled) and if you have copied a lot of data recently. The MCH may also be stuck doing some Plex processes (if enabled). In those cases, you should wait, otherwise try to do a reboot or power off. There is no good way to reboot if the webapp or mobile app cannot access the MCH. Normal commands to access the MCH in the codebox you can try:

  download debug_logs  yourMCHip is the ip address of your MCH
http://yourMCHip:33284/cgi-bin/logs.sh

  reboot MCH
https://home.mycloud.com/settings/current_device/reboot

  shutdown MCH
https://home.mycloud.com/settings/current_device/shutdown

This is a similar situation to that of the My Cloud, a different OS than MCH, but worth a quick look. Note that the MCH has no SSH available to the owner other than logs.sh:
