Server is too slow when i use a VPS Gateway

Hello, how are you?

I am having an inconvenient with a VPC Gateway, following the guide https://docs.digitalocean.com/products/networking/vpc/resources/droplet-as-gateway/ , I implemented all the steps, but by integrating a server within the vpc network and redirecting traffic through the gateway server, I have problems with my application that is running on apache, because only when I access the link works quickly and after that all HTTP requests are never called .

Design Implemented: https://docs.digitalocean.com/products/networking/vpc/resources/droplet-as-gateway/

I leave information of MTR Report from Server inside the VPC:

mtr --report google.com
