The Remote Access test says "The External DNS/IP address could not be found". What's wrong?

In short

Most often the address was typed as a web link. External DNS/IP takes a bare host name or IP address, such as myhome.ddns.net, with no http:// or https:// in front and no slash at the end. With a prefix, Roomie looks up the wrong name. Both the test and real remote connections then fail.

Where the setting is

Settings › Homes › your home › Remote Access › External DNS/IP. Roomie adds the port (47149) itself, so enter only the name or address.

Right and wrong

Right: myhome.ddns.net, or your public IP address on its own. Wrong: https://myhome.ddns.net, http://myhome.ddns.net/, or myhome.ddns.net:47149. Delete any prefix, trailing slash, or port number, save, and run the test again.

If the name is entered correctly

Then the name itself isn't resolving. Check the spelling, and make sure your dynamic DNS name is still registered and is being updated by your router or NAS. Free dynamic DNS names often expire unless they are renewed.

Other results you might see

"No answer … on port 47149" or "Could not connect" means the name was found, but the connection didn't reach your Primary Controller. Check that TCP port 47149 is forwarded to the Primary Controller's local address. Some routers can't loop a connection back from inside the home, so if the test fails at home, try Roomie on cellular before changing anything else.
