Custom port doesn't work on CSS and JS files

SOLVED
if you want to use other port than 443, read this what i hope save you some time.

– i realized that, for some reasons plugin didnt want to save my port settings to database
– i manually changed in table wp_options field named ‘wordpress-https_ssl_port’ to ‘2443’ (my custom port) – it didnt really help, but
– i manually changed in table wp_options field named ‘wordpress-https_ssl_host’ from ‘https://domain.com/’ to ‘https://domain.com:2443/’ – and that worked

I didnt have enough time to analyse why these settings work, the plugins author would know best, but it works properly without any problems.
