Clicking "help" in online questionnaire leads to error message

Dear survey solutions team,

I am testing my online questionnaire and wanted to see what the “help” button on the top right hand side of the screen does. It refers to https://docs.mysurvey.solutions/, but I get the error that my connection is not secure (using firefox and explorer) - see screenshot below. Is this a problem with my computer or is there something wrong with the link?

Many thanks,

Sebastiaan

I have the same when I try it.
