google static maps with enc path is not always working

i have implement a static map that show a route based on

routes[0]->overview_polyline

and i also have add the start and end markers

The problem is that is not always working and i assume that there is a problem with overview_polyline but i can not figure out

This is a working static map that show both markets and route

Its only displays the markers without the route

i have implement the code from here Google static maps with directions

Can any help me make this work, any help appreciated

Solution

When I check the encoded polyline from the second example in the Interactive Polyline encoder utility

https://developers.google.com/maps/documentation/utilities/polylineutility

I can see that the route is located somewhere in the sea as shown in the screenshot

Can you post the original Directions API request that returns this encoded polyline, please?
