Web page wont display in lovelace web card

I’m wanting to display the local boat ramp conditions in lovelace.
If I enter the following url in my browser(s) the page displays fine.

if I create a web card and enter the same url I get www.boating.vic.gov.au refused to connect and of course nothing displayed.
how can I fix it as the browsers work fine.

I get exactly the same… did you manage to fix this?

Nope not yet, sorry. Really disappointed in the lack of support out there.
I’m trying to find out the permissions needed on the file to see if there is a problem there.
Would appreciate hearing from someone who does display the image file correctly to confirm their permissions/ownership

I’ve been getting this problem too, Can’t seem to load any webpages using that card. Any support greatly appreciated.
