Teb_local_planner feasibility check always fails

I am using movebase with teblocal_planner but on every goal I get the same result first teb says the feasibilty check failed with the following message

[ WARN] [1525093179.924067116, 152.844000000]: TebLocalPlannerROS: trajectory is not feasible. Resetting planner...

This is repeated until recovery behaviours are attempted, these also fail with the following messages :

[ERROR] [1525093221.607037380, 168.074000000]: Rotate recovery can't rotate in place because there is a potential collision. Cost: -1.00

So it seems the robot thinks it is on an obstacle while it's not, because this also happens when the map is empty.

the feasibility check uses the footprint model defined in your costmap_2d configuration. Have you checked that? You might also compare your navigation config with the tutorials package.
