Sorry i tagged this with 1.14.4 as i am unable to tag issues for Legacy versions of the game where the issues are external to the game.

Old versions of the game are unable to function due to the old Authenticaiton servers being offline: https://login.minecraft.net/session?name= 

This can be simply fixed by allowing that old Auth URL to work the same as http://session.minecraft.net/game/joinserver.jsp?user=

This issue results in Leagacy servers having to use AuthMe and other methods that also allow illegal and cracked clients on to servers.
