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

研究方向
Investigate the TLS listener configuration in AdGuardHome's source code, particularly the port binding for DNS over TLS. Check if there is a known issue with RHEL or specific kernel settings. Look at the code responsible for starting the TLS listener, likely in the `internal/dns` package. Also review any existing discussions on GitHub about port 853 issues with similar setups.
