Can't access WebUI after reboot

[fredrick-plc]

Hey all, I just switched from PFSense to OPNsense and got everything set up. I wanted to test to make sure everything came up after a reboot, so I went into the WebUI and rebooted. Upon booting OPNsense again, my internet connection and all networks are working, as well as firewall rules. However I can't get into the WebUI. Firefox and IceCat both fail with the same error code:

Code Select Expand

MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSING

My WebUI is HTTPS (I think it was by default) so I am unable to access it via HTTP. I can SSH into it just fine. I've tried different browsers, clearing history, and removing previous certificate exceptions from firefox. Any ideas before I throw in the towel?

Thanks

If you can access via SSH, you can revert the Webui to HTTP, or generate a new self signed certificate.

I reverted it to HTTP and was able to get in an export the config. Thank you!
