URL with double dashed error [Ubuntu with ngnix ]

Good morning everyone,

I have encountered an error when I double dashed the url.



In localhost it works perfectly, when I deploy the project in Ubuntu + ngnix it gives me an error only in the ur with double dashed.



example: www.dominio.com/pain-relief/car-accident-injuries



Image error Ngnix

If I open the project on my Windows PC + Xampp it works perfect.

Greetings 

PD: Any guide on how to insert images?
