Cannot set up Private AppStore

Dear all,

I cannot set up Provate AppStore. I have followed all the instructions, however, nothing helps. 

I also went through these suggestions  https://community.rws.com/product-groups/trados-portfolio/rws-appstore/w/wiki/6403/private-appstore  and

everything seems OK but it's impossible to set up private appstore. I have Windows 11.

What else should I try?

Many thanks in advance,

Maarja
