Mixed Content: The page at ' https://auto-dina.ru/purchase/finance/credit/calc/?back_url=~y7YDI&pl=Y&MODEL=touareg&COMP=touareg_v6&PRICE=3598500 ' was loaded over HTTPS, but requested an insecure resource ' http://cars.volkswagen.ru/credit/garant/touareg/?complect=touareg_v6&price=3598500&mode=iframe&view=no-form '.

Answer 1

I found that URL hadn't slash '/' after model code. Apparently, on requested site in .htaccess file rule for redirect to '/' is above https rule, or something like that. In any case, adding slash in URL address solved my problem
