Snap docker

I installed the docker snap recently and seems working fine except for the fact that if you have this Dockerfile

FROM python:3.10
RUN pip install pydantic

it fails to fetch the module I tried to debug what’s going on seems like the pip is returning this:

Getting page
Starting new HTTPS connection (1):
Incremented Retry for (url='/simple/pydantic/'): Retry(total=4, connect=None, read=None, redirect=None, status=None)
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f4155179c00>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/pydantic/

My connections of docker says:
