I starting facing this issue some days ago. Even when the firewall is down, I can't reach my mac from my local network. Ping is not responding neither. Some test I've done:
From my console
nrossi@~$ netstat -an | grep 8080
tcp46 0 0 *.8080 *.* LISTEN
nrossi@~$ sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate
Firewall is disabled. (State = 0)
nrossi@~$ ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}'
10.1.2.123
nrossi@~$ curl -I 10.1.2.123:8080
HTTP/1.1 200
Content-Type: text/html;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 18 Mar 2021 13:06:46 GMT
From other computers
nrossi@~$ curl -I 10.1.2.123:8080
curl: (7) Failed to connect to 10.1.2.123 port 8080: Operation timed out
nrossi@~$ ping 10.1.2.123
PING 10.1.2.123 (10.1.2.123): 56 data bytes
Request timeout for icmp_seq 0
Any help ?

The checkpoint extensions was my first candidate to remove. So I run the uninstaller:
Everything is working fine now.
