I installed Vessel View Mobile on my boat. Recently I experienced a few CHECK ENGINE SHIFT ACK alarms and Vessel View Mobile registered these on my iPhone app as CHECK ENGINE. However, it gives no other info. Furthermore, whereas I am connected to the internet it says "Please check your internet connection and try again". I know I am connected to the internet so I can't understand this. The only thing I can think of is that I/boat am located in Turkey and may be Vessel View Mobile is limited in its coverage.

Any advice will be appreciated.
