Contantly getting 503 Service Unavailable when accessing WebGUI

[kr33]

Hi All,

I am struggling with an issue where I constantly get the "503 Service Unavailable" error when trying to access the WebGUI. I have to restart all services to get access to the GUI again. (before enabling SSH I had to physically restart my device). I've added a screenshot to what I see.

I still have internet access when this happens so not sure where to start looking, I'm pretty new to OPNSense.

Any guidance is highly appreciated.

Hello,
I have same behavior.
after a while, I have the error 503 and I can see on log file that
lighttpd was complaining that socket 127.0.0.1:443 is  already in use.
And yes I verified with sockstat that the socket is already in use by lighttpd .
I restarted opnsense, I am able to login on webgui from a short period and from the dashboard webgui is marked stopped !!
Very strange behavior because after a while, the 503 error happened again.
As from the previous version, it was working fine all the time. I checked what was wrong.
Using ssh session, I tried to restart all service but it failed to start webgui.
So to solve this problem, from command line :
sockstat shows lighttpd running and listening on the right port
I stopped the lighttpd process using kill command.
I started the lighttpd using /usr/local/etc/rc.restart_webgui.
now I am able to log in webgui and it is shown as running from dashboard.
I don’t understand why just after a reboot, dashboard is showing webgui not started even if lighttpd is running and listening on all sockets for the right port( listening on loopback, lan and wan addresses)

A quick update on this from my end.

I had DHCPv6 enabled on my VLANS, after disabling it, it seems like the issue has not occurred again for the last few days (Crossing fingers) :-)

Now I have another issue (for another post)
