To troubleshoot networking issues:
Steps
-
Check traffic coming to the appliance:
tcpdump -nni eth0 tcp port 443.
-
Run Wireshark on the Windows machine simultaneously to capture traffic on the FSAM interface. Filter on port 9443.
-
Reload, restart, and check the status of the nginx service on the appliance.
#systemctl reload nginx
#nginx -t && systemctl restart nginx
#systemctl status nginx
