This change is discussed in the Jan release notes.
Connect can only be used with https
listeners (customers' servers).
And note that the server must use a certificate that chains to a root cert in the Microsoft standard root cert list. (Self-signed certs won't work.) You can use a free cert from LetsEncrypt or a $15 cert from a reputable CA.
I'm sorry that this update caught you by surprise.
