Changes to inbound rules are not updating to instance

Question

In the AWS management console I have a single instance. When I go to that instance's description and click view inbound rules I get:

80  tcp 0.0.0.0/0       ✔
22  tcp 24.47.137.69/32 ✔
443 tcp 0.0.0.0/0       ✔

If I go to that instance's security group -- only one -- and delete the port 443 rule, it get's deleted from the security group, but when I go back to the instances page and click view inbound rules again, I get the same thing:

80  tcp 0.0.0.0/0       ✔
22  tcp 24.47.137.69/32 ✔
443 tcp 0.0.0.0/0       ✔

Any idea why the instance's inbound rules aren't updating when it's security group's is?

Answer 1

Removing the security group and then reassigning it to the instance did the job.
