Errno 104 Connection Reset by peer in python3 requests executed in a VPS using Ubuntu20

After backtesting in a windows laptop using python3 that the code worked fine, I uploaded the code to my recently purchased VPS service. I installed pip, python3 and the requests module (among others) only to find that when I try to run the script from the server terminal it returns the title error. It also returns the same error if I open python3 in the terminal of the vps and manually try to make a python3 request

## Expected Result

I expected to be able to conduct a simple python request running python script in a VPS that makes use of Ubuntu20

## Actual Result

What worked perfectly in a windows pc returns an error when executed by the VPS

## Reproduction Steps

```python
import requests

url = "https://www.adidas.es/api/plp/content-engine?query=ultraboost-hombre"
headers = {
