Open Nuetral on Surge Protector

My surge protector light shows I have an open neutral. I have had the issue at 3 different campgrounds. The light doesn't come on when I plug into the electrical outlet but when I plug in my 30 amp cord it comes on.
Could this be caused by a broken neutral wire on the 3 prong plug on my side or would it only be caused by the source?
Thanks for any help..

Although it's highly unlikely a main service cable manufactured with sealed ends will have a broken connection inside it's also not totally impossible but the solution is simple - just measure it with an ohmmeter.

Unfortunately you've provided little detail, such as the exact make / model of surge protector you have, whether you're also getting this so-called error when plugged into a known shore power source that is correctly wired, whether the surge protector still passes power regardless of the fact it sees what it thinks is an error, or whether you've tested the system with the surge protector entirely removed. What you're calling an "open neutral" may actually be a case of bonding, or more correctly lack thereof, and how your particular surge protector deals with it. You might want to read through this recent discussion I started on the subject, in my case how bonding may be an issue when using an inverter to power a trailer ... regardless, it's important to understand even if you only ever run on shore power.
