Importing a Private Github Repository Stalls

Upon specifying the private repository on GitHub it starts the process to setting up and initializing which never ends. That starting page hangs without progress
for many hours.
I saw this topic once raise back in April but they at least had some errors returned.
Here is just don’t know what is going on.

Does it even suppose to add [my] private repo?

Hi @AleKo - does the browser developer console show any errors?

It got stuck on this page (initializing step), i don’t think there is “developer console” available.
