Thanks for all your help! I have transferred over to DNSimple and have moved a step further. Both tweaky.app and www.tweaky.app are now in the connected state using Webflow Free SSL.
However now when I visit them I get an ERR_SSL_PROTOCOL_ERROR in Chrome and the following screen shot complaining about an expired certificate in Safari.
Thanks! I have waited for propagation to happen over night, and can confirm that whilst not totally propagated, it has propagated to my current DNS. I have tried to access my site from my current location, and my proxying to various different locations and all give me the below error:
To try and debug this I have bought another .app domain shipd.app, and set that up on the same project and it works fine almost instantly. I am still unable to get tweaky.app to work, this is starting to look more and more like an issue Webflow end. Can somebody check my account and ensure that SSL is setup correctly for tweaky.app please?
It seems that I do, especially since I type in tweaky.app and it successfully redirects it to www.tweaky.app as I had defined in Webflow. I have followed the exact steps outlined except one works (shipd) and the other does not (tweaky) please see attached
According to Google G Suite toolbox you don’t. That would indicate a propagation problem, since they are the default registrar for the .app domains and where you registered yours. The whois for that domain does show the new nameservers.
See screenshots.
