"Not Secure" in Google websites. FTPS/SFTP

[Riftvalley]

H,

I notice that there is a "Not secure" warning when I publish a site to Google, does not appear in Firefox, or Edge. How can I avoid this (or make my sites more secure).

I have tried FTPS and SFTP in the "Other web hostings" dialogue, I think it was the SFTP that worked OK.

Is this a Xara issue, or do I have to talk to myhosting company 1&1?

Kind regards
Martin
