A few years ago, I checked the propane tanks (always covered since new) just before a trip 'cause the frig wouldn't light on propane.
As I pulled off the cover, I noticed the short connector hose on one tank had blown apart from the crimped fitting near the switch over gizmo and lost all the propane in that tank.
IN a pinch for time, I secured it with a small hose clamp that proved leak free after installation & re-filling the tank.
As first opportunity, I replaced the hose with a new one...no issues since.
