<![CDATA[[SOLVED] Is there a limit for captive portal instances?]]>I have 8 captive portals, every one on different vlan.  But one of them can't be restarted. I even tried to recreate it and it still presists. The other 7 work perfectly fine. What can I do here?

Twice zoneid "4", so nginx uses 8004 as a port twice and that won't work.

Export you config.xml - change the last line "4" for a "16" and re-import.

https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting

You might want to post the output from some of those.

It looks like there is already something listening on 8004 for whatever reason.

ps axww | grep nginx See if there's already a process using /var/etc/nginx-portal_4-CaptivePortal.conf as a config file. Maybe kill it if so. You can look at the files and see what the listening ports are, but 2 should be 8002, 4 should be 8004, etc.
