I have a VM in Azure running Server 2016 with Active Directory Domain Controler. (Not Azure AD! But AD role setup on a VM!) and for this I use our public domain intra.test.online (I didn't share actual domain name!) . For some reason I'm no longer able to join any machine to this domain and it worked before? I get the prompt asking me for user name and password and then I get the error "The Network Path was not found". I did try disabling FW on both sides, and adding Azure VM's public IP as preferred DNS in local VM but still get the error!
