EGR Valve problem Hose keeps blowing off the bottom of the egr valve.It first s on 1997 Toyota RAV4

Hose keeps blowing off the bottom of the egr valve. It first started when the port of vaccum got hot and melted so I replaced it then I replaced the vaccum modulator because the hose kept blowing off it. Now the hose is blowing off the EGR valve so I replaced it but it is still blowing off.
