go get and AzureDevOps authentication not working - go

Question

I am desperately trying to figure out why a go get command from a package residing inside a Git repo on AzureDevOps does not work.
Both golang projects (the project where the package resides as well as the consumer trying to import it) are located inside the same AzureDevOps project.
I am attempting to import a package from the one into the other but alas with no avail.
I followed the instructions found here: https://learn.microsoft.com/en-us/azure/devops/repos/git/go-get?view=azure-devops
I have created a PAT and tested that I am able to clone the repo from where I want to import the package from, and that works fine.
git clone https://me:78rt5u89dg635ef4fb30e4b0229e4329756986416673b4e331ag#dev.azure.com/my-comp/my-proj/_git/k8s-team-operator
So I have in my mind (maybe incorrectly so) made the assumption that the PAT is able to authenticate correctly. That said, I unfortunately have to use cntlm proxy to get to the outside, but this works well in general.
In my golang project inside the terminal I have set : export GOPRIVATE=dev.azure.com
In my GitConfig file located at location ~/.gitconfig I have set the following values:
# This is Git's per-user configuration file.
[user]
email = me#my-comp.com
name = Morné Kruger
[core]
editor = vi
[url https://me:78rt5u89dg635ef4fb30e4b0229e4329756986416673b4e331a#dev.azure.com/my-comp/my-proj/_git/k8s-team-operator]
insteadOf = https://dev.azure.com/my-comp/my-proj/_git/k8s-team-operator
I then run the go get command with the verbose flag, and then get the following less positive response:
