Good day

I have a clean install on a Small Form Factor Dell with an i5 8th Generation and 20GB RAM, with an Intel X710 network card.  I have configured two interfaces (WAN and LAN) with DHCP server running on the LAN.  I have enables SSH access on the LAN.  The router seems to perform very well and fast for a few hours before I receive a popup stating "Danger. Unexpected error, check log for details error on (almost) clean install." (shown below)

When I clear the popup, I get a few seconds before it returns again.  All of my logs appear to be empty.

I have tried to follow the troubleshooting suggested in thread https://forum.opnsense.org/index.php?topic=45194.0 as follows:





Can you look for the PHP_ERROR (I dont know if its exactly called like that) file in:

/tmp/

And look for the last entries? If you post them we could see what the error was.

Can you execute this from the shell?


CodeSelect
/usr/local/opnsense/scripts/routes/gateway_status.php


Please post the array it returns. When it returns nothing or ERR please look at the PHP_errors.log again and post the error.

Sorry I forgot to ask for

CodeSelect
configctl interface gateways status

Even though you get an array from the above php script it executes, maybe this casts ERR?


root@OPNsense:/ # configctl interface gateways status
error in configd communication, see syslog for details











Can you try a different browser or incognito mode? If the PHP error reappears each time it's a bit strange the backend call that is supposed to be failing is working fine. Otherwise the browser likes to cache an old invalid response for whatever reason...


Cheers,
Franco



No difference with Chrome Incognito Mode, Edgo, Firefox, Samsung Browser.

A list of interfaces you get get using:

# ifconfig -l

I'm sure there is one that's causing all the trouble.

root@OPNsense:/ # ifconfig -l
ixl0 ixl1 em0 lo0 enc0 pfsync0 pflog0


pluginctl -D xxx on all these interfaces produces something similar to

When I ssh in and select option "11) Reload all services", everything seems to come back online for a few minutes before the error returns.  During all of this, Internet access is not disrupted.

Incidentally, as part of my troubleshooting, I have tried substituting a different computer, network card, RAM, NVME drive and even new installation media with a complete reinstall but the error returns after a few hours.  Is my network cursed?! :-)

Thank you in advance for any ideas you may have.

Sorted.  It would appear that if one accepts the prompt to change between http & https the first (and only) time one allocates IP addresses to interfaces the whole WebGui becomes completely inaccessible with the only solution being reset to factory settings or reinstallation.  Good to know!

I tried accessing it with http://192.168.2.1:80, https://192.168.2.1:80, http://192.168.2.1:443, https://192.168.2.1:443 from multiple different devices, computers and browsers (all with great internet access through the OPNSense router) with no success at all.

Thank you to everyone that offered advice.

Can you ssh to the FW?

I can't SSH in as it's disabled by default and I've no idea how to enable SSH access from the console!

So you can at least console?

If yes, try to reset the default access via console.

Yes, I can access by the console - everything seems to be working with the exception of WebGui access!  Thank you.  I'll give that a go when I get home this evening!

Did you enable https during the setup?
If so, your browser possibly doesn't accept the self signed certificate due to its security configuration.

You can try another browser.
If you cannot change the browser, login into the console and go through the LAN IP assignment and enable HTTP for the web GUI access.

I've tried several different browsers on several different devices - computers, phones, tablets.  None of them can even get to the "unsafe site" warning.  It's as if there's no web server enabled!

Are you connected to the LAN interface?
Do you have internet access through OPNsense?

What do you get in the browser?

LAN and WAN interfaces are correctly configured.  I can ping the router without issue.  Internet access is perfect for all devices on the LAN.

I can't access the WebGui on the router from any device on the LAN!  Browser sits doing nothing before reporting "This site can't be reached".

Hi all.

I'm comparatively new to OPNSense and have been playing with it for around the last month.  I did a clean install a few days ago and my network is working beautifully.  The only issue I have is that I can't access the WebGui from my LAN.  All of my network clients are getting their IP addresses from the OPNSense DHCP server and working perfectly.  I can PING the server but I cannot get any response to its IP address in a browser.

I have reinstalled completely three times now, but nothing changes.  I even tried changing the RAM and drive in the computer and using a different USB drive to install the installation media onto.  I even checked the downloaded file hash!  Everything was working before I did the clean install.

If I had much hair, I'd be tearing it out!  What could the issue be?

Thank you in advance for taking the time to help me out.
