March 5, 20251 yr Periodically, I've found if I leave a web browser tab up looking at either Dashboard or Main or Docker tabs (6.x and now 7.0 since beta 1), there's a good chance I can get the whole GUI to crash. If you google "Unraid GUI unavailable" or "Unraid nginx crashes" or "how to restart unraid GUI", there are dozens of posts from people experiencing the issue, usually coming to the conclusion that they need to restart the server to get the GUI back. nginx is throwing the error, so many people have recommended running the following to restart the entire webserver: /etc/rc.d/rc.nginx restart However, this has never fixed my issue (and I haven't found any obvious crashes in my logs), so I've ended up rebooting, which is tedious and disruptive. However today, deep in another forum post, I found this process (run by ssh'ing in to the server and running as root), which corrects the root cause for my GUI issues without a reboot - a PHP crash: /etc/rc.d/rc.php-fpm restart Now I know to look for PHP errors the next time this occurs, and can hopefully help contribute to identifying root cause... but in the meantime, I'm hoping this post bridges the gap on web and forum search results to help others as well.
