Description

I am using RHEL-8.6.0 system in aws ec2, I have configured ssl certificate, ec2 security group has squared port 853. Port 853 is not working, I check that port 853 is listening, no firewall is enabled, but port 853 is always in filtered state. I use nmap to scan 127.0.0.1 and find that port 853 is in open state, but when I use nmap to scan public ip, I find that it is in filtered state. Is this a problem caused by incompatibility with RHEL-8.6.0? Sorry, I forgot to mention

@SuAdnim Is the ec2 security group configured to allow incoming traffic on port 853?
