It could be due to the fact that you have set one or more parameters of your peer.properties file with a wrong value.
Please accurately check the values of your peer.properties file.
A common mistake is to specify latitude/longitude values as DEGREES MINUTES SECONDS form in place of DECIMAL DEGREES one. For instance, if your peer is located at coordinates:
latitude: 41° 52′ 00” N
longitude: 12° 37′ 00” E
in order to set these value inside the peer.properties file, you have to write:
peer.latitude: 41.87
peer.longitude: 12.62
The convertion from DEGREES MINUTES SECONDS to DECIMAL DEGREES can be performed with the formula:
DECIMAL DEGREES = DEGREES + MINUTES / 60 + SECONDS / 3600
