[Python] Docker fails when trying to install libraries

I am trying to build a docker image and it fails in the

RUN pip install -r requirements_inference.txt


The error message is

182.3 ERROR: Could not find a version that satisfies the requirement pytorch-lighning==1.2.10 (from versions:none)
128.3. ERROR: No matching distribution found for pytorch-lightning==1.2.10

ERROR: failed to solve: process "/bin/sh -c pip install -r requirements_inference.txt" did not complete succesfully: exit code: 1


However when I create a conda environment and activate it I can do the pip install of said version without problem

What is the problem with docker ?

EDIT 2: According to this question this might be related to the WIFI I use... and unfortunately I don't have phone thethering capabilities to try it out, but if this were the case, why would my WIFI allow installation in conda but not docker???

EDIT: I have been asked a minimal reproducible example. I dont think it exists but just in case this is what I am using
