<The page couldn`t be loaded> for Auth 2.0

Guys, I really like SOAP UI, but first of all I have tried to setup authorization via Auth 2.0 in free product, version 5.2.1, then I have repeated it in 1.8.0 free trial...

In any case I got "We can`t open this page" and "The page couldn`t be loaded", I thought it`s only in free version, but no.

I made the same setup in Postman and it works, I can see 'id_token' and 'access token'.

Do you have any resolutions?
