Building w/ docker stuck at "Searching for an ION_UPDATE_SERVER"

[deeKal]

Hello,

I am trying to build TS Analysis module using docker container, following the instructions here.
The building doesn't go on much and after the first "Searching for ION_UPDATE_SERVER" gets stuck, like this:
`Building TSS packages: Analysis

It had been stuck since last night (for more than 16 hours) and now I tried to rerun it and it gets stuck again.

Thank you!
