Clean install: traffic is routing really well but no WebGui access

[roohoo]

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.

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".

Can you ssh to the FW?

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

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!

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!

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.
