C2_W1 Programming Assignment

Hi I’m working on C2_W1 assignment of the Introduction to Data Engineering course and got stuck from 1.12, I think I might accidentally delete the inbound rule for the de-c2w1a1-rds database because I can only the outbound rule under Security group rules section, just wondering how I can fix this issue? I tried reboot but it seems not working…

Hi @Lixian_Wu ! Don’t worry, it happens to the best of us.

Looking at your screenshot, it seems the Inbound Rules are just missing, which is why the connection is blocked.

so,A reboot won’t really help here since it’s a network thing.

I see that you try clicking that blue Security Group link (the sg-xxx one) and add a rule to allow traffic.

You can check this official AWS guide for more info:
Controlling access with security groups

It should work fine after that! Let me know if you get stuck again,I wish you a happy coding and hope you finish the assignment!
