Microsoft Edge cannot connect to URLs that resolve to 127.0.0.1

I read that Edge cannot connect to http://localhost, but I've already solved that one using about:flags and "allow loopback" .. it doesnt solve my current problem though

My company has a domain localhost.mycompany.com that is set in DNS to resolve to 127.0.0.1 We use it because we have login.mycompany.com that sets a domain auth cookie, so when we're debugging on local machines, we can use the login.mycompany.com to set the cookie, then proceed to localhost.mycompany.com:xxxx (where x is a different port number depending on which web app we're debugging)

Has worked fine in all browsers over the years but I note that even though Edge will connect to http://localhost:12345 it will not connect to http://localhost.mycompany.com:12345 (which is vital for it to submit the cookie login.mycompany.com set)

What can I do to get Edge connecting to this address?

In a related post Why does Microsoft Edge open some local websites, but not others, where the domain name is routed to 127.0.0.1 in hosts file I found a DOS command snippet:

CheckNetIsolation LoopbackExempt -a -n="Microsoft.MicrosoftEdge_8wekyb3d8bbwe"

Running this in an elevated CMD seems to have solved the problem
