I'm running 25.1 after this also happened on 24.7. I don't have a console cable adaptor so I just reloaded OPNSense. I have made no other changes to settings/services/firewall rules etc beyond adding a TOTP server and OTP to each access account. I was trying to set up IDS/IPS which, as it states first requires disabling all hardware offloading in Advanced Network. I did this, saved, then Enabled IDS and IPS, Enabled syslog alerts, set pattern to Hyperscan and set Interface to LAN. Web gui appeared to freeze up after saving and reboot didn't fix and is now totally unreachable.
Any advice is very appreciated!!
