Installation with external hub at Youtrack

(I checked with incorrect username/pwd -- it fails right away). 

However, the button "Next" does not become enabled and I cannot proceed further.

I checked "Readonly" mode on Hub side, it is disabled.

In Hub logs I see the following:

I checked that computer name resolves into ip by short name, fqdn, alias, etc.

Can you please advise on this issue?

Thanks.
