Ubuntu server UFW issues

br flag
AdhamH99

I was sending requests to my server using postman. Then, something went wrong and all of my requests were blocked. Now, I can't send requests or even access the server using the IP address unless I use a VPN.

I am a student learning and I am pretty lost — I don't know where to start. I searched for hours on how to reset UFW and disable and enable and even adding new rules didn't work. Below is the output from the UFW iptables. I'm sending requests through postman to the server IP.
