Hi all, we have FreeNAS-11.3-U4 (72296567b9) running quite stably since we upgraded from 11.3-U3.2 in July), except for one issue that's just occurred for the 2nd time in a month: for no apparent reason, the web GUI just stopped working, such that pointing any browser (tried both Safari and Chrome from MacOS 10.15.7 Catalina) to its usual URL only gets this screen:

As happened last time, the system is still chugging along fine, and I can SSH into it normally, so it just seems to be a failure of the web GUI service somehow.

Last time this happened, tried restarting nginx service, but that didn't work, so ended up rebooting and that fixed it.

Would really like to find a fix that avoids a reboot: any suggestions?
