error at creating embedded page

[animus888]

Whenever I try to add a new embedded page I get following error at the end:

Further information: I'm using Plone 5.2.4, latest collective.embeddedpage (=2.2.1), the html file in the url is very basic... Thanks!

I got it all in a Docker container, maybe I cannot access the url inside the container and that's the problem... will check this

it's not really an issue. When I use docker run --network host... for my Plone container, then everything works fine with adding an embedded page. Maybe you can add this to your README ;-)
