uMap embedding (custom OpenStreetMap maps)

Continuing the discussion from OpenStreet maps embedding: I want to embed the uMap below, but it’s not working. I added the domain ( to the “allowed iframes” but that only shows the “See full screen” link in the post, not the iframe. I also added to the allowed embedding list. No effect either.

<iframe width="100%" height="300px" frameborder="0" allowfullscreen src="//"></iframe><p><a href="//">See full screen</a></p>

Native OSM maps do work (see below), as well as Google Maps.

<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src=";layer=mapnik&amp;marker=39.7240885773337%2C-68.642578125" style="border: 1px solid black"></iframe><br/><small><a href=";mlon=-68.643#map=6/39.724/-68.643">View Larger Map</a></small>

What could I be missing here?

Ah… I needed to add https to src="//, by default that’s not included in the share menu on uMap.
