Flashed vanilla openwrt as suggested to enable UX wireguard packages. Changed lan address to 192.168.8.1 . Now no web interface to login. Can login ssh.
Changes to address would not accept until I did 'unchecked' apply.
rpcd fine, applied permissions to shadow file (web root still white blank), hesitant to muck with password reset, uhttpd not empty, cookies relevant (open in new container tab to luci web)
