I have created a provider-hosted solution and added an addinpart (aka client webpart, aka app-part)
Im debugging this using a SP Online account I works fine in IE and Chrome but on Edge I get an error message "Hmm, we can't reach this page.", Try this Make sure you’ve got the right web address: https://localhost:443xx
Any idea why? Is this a debugging problem only or will is still be a problem on production environment?
I did "reinstall" Edge using this guide, but no difference
