Connection problems to AWS after moving

Hello, as the subject says, I recently moved into a new apartment and my ISP assigned me a new profile. I'm not sure why, that's just how they do it. I have the same router and everything. I use winSCP to transfer files to my Foundry VTT, which is hosted on AWS. After moving, I can no longer connect to Foundry. I get the error message

Network error: Connection to " [AWS public IPv4 address] " timed out."

and no other dialogue. Will I need to reset something on the AWS side?

I followed this guide for the AWS setup: https://github.com/cat-box/aws-foundry-ssl/wiki

Fixed issue by editing the security group rules to include my new IP address. lol.
