Ports page gateway timeout

We recently upgraded to a new server by installing LibreNMS and importing the database and copying over the rrd files. Everything works great except when clicking on the ports page for any device will bring up the 504 Gateway Time-out. No other page seems to have that issue.

I increased the timeouts for nginx and php-fpm to 5 min. The ports load for some devices but still times out on other devices. I could not find a correlation to devices and the number of ports. Some devices with a couple hundred ports would load immediately while other devices with 5 ports might time out.

After much troubleshooting and frustration (lol), I ended up testing the changes from here https://www.coryfiala.com/fix-slow-loading-pages-graphs-librenms-ports/. Essentially I commented out ifInNUcastPkts and ifOutNUcastPkts from the shared_oids in ports.inc.php. Ports load time went from timing out after 5 min to around 30 seconds. This worked great except that it broke updates. Now to figure out why those oids break it.
