In Plesk Manager for Android the following error shows up when trying to connect to the server:
(unsupported version) code 1005 "Protocol Version '184.108.40.206' is not supported. Current protocol version is 220.127.116.11. You should upgrade Parallels Plesk Panel Server Manager"
Plesk Mobile Server Manager 1.4 supports only Plesk 11.x (KB article #116248 ) because Plesk 10.x doesn't have extensions SDK.
Upgrade Parallels Plesk Panel to version 11.5.
