As far as I see there's no PTR record for your new IP address yet:
mh1:~# dig -x 220.127.116.11
; <<>> DiG 9.2.1 <<>> -x 18.104.22.168

But I think your error is caused by DNS not being updated fast enough. DNS changes can take up to 72 hours until they are propagated, so maybe you might have to wait a little bit longer.
