I have tried to change the A record but the values did not propagate despite 24 hours passing. When I tried to change the TTL, there’s no such option in the DNS. I tried deleting previous A records and creating new A record, it still did not work. I tried to delete the whole website and add a completely new website, it still did not work despite 24 hours passing.
Any suggestions as to how can I speed up the DNS changes propagation process?
