GoogleMaps refuses to connect

Are you using the X5 object for the map?

In Google maps you can click somewhere on the map  and you will see this

You can then choose 

Integrate - and then you will see code for integrating it on your page.

You are not using https and therefore this is the case:

{ "error": { "code": 403, "message": "SSL is required to perform this operation.", "status": "PERMISSION_DENIED" }}

I suggest you change to https

It seems you have also a site here: https://www.hify.online/map.html

Try changing the link : 

http://maps.google.com/maps?hl=en&f=q&source=s_q&geocode=&q=&t=m&ie=UTF8&hq=&hnear=&output=embed

to

https://maps.google.com/maps?hl=en&f=q&source=s_q&geocode=&q=&t=m&ie=UTF8&hq=&hnear=&output=embed

page and link in iframe should be https - Google does not like http

Maybe you do not have the correct code for embedding. The source requires same origin to be shown.

Refused to display 'http://maps.google.com/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.

Thank you!
