@email@example.com @sturmflut Nah there's no risk, there just might not be a place on the page where it makes sense to add an extra visible link.
@sturmflut @firstname.lastname@example.org It seems you don't actually have to put a visible link. A <link> tag in the <head> section also seems to work, or at least it worked for me when I did it.

@email@example.com from https://www.geeksforgeeks.org/maintain-the-aspect-ratio-of-a-div-with-css/ - put padding-top:56.25%; position:relative; on the <center> container, remove the <br>, and the <iframe> position:absolute left:0 right:0 top:0 bottom:0 width:100% height 100% - seems to work
@meduz if you're using certbot --webroot, try using certbot --nginx instead - it should be able to temporarily override the redirect just for just the acme challenge url
