Hello,
My site is having trouble loading images in the 'Problem Library' section of WebWork. I looked a the console in my browser and see the crowser is timing out trying to find the image. Where would I look to troubleshoot this problem. The issue also makes loading other questions on the 'Problem Library' page load slow.
Console output:
Any help would be very appreciated.

I don't see the console output in your post. Can you try pasting it as plain text?
GET https://XXX.X.XXX.XX:8080/wwtmp/TEST_LOGIN_331//images/afee334b-282b-3807-a50c-1a8e4c8bd79f___87700c28-268c-33f3-bb2b-dd7e33198cda.png net::ERR_CONNECTION_TIMED_OUT
This is what I see in the browser output.
I am have almost this exact same problem. All images are loading if I am connected to the same network as my Webwork server. If I am connected from outside the network formulas display, but other images such as graphs do not. Instead I get the error Failed to load resource: GET https://webwork.hopkinsschools.org:8443/wwtmp/AP_Calculus/images/26f1a20e-223c-3c7f-b1db-919070383517___2856e0a2-ab6e-3e60-af3c-710f82a5c79c.png::ERR_CONNECTION_TIMED_OUT. This occurs in Edge, Firefox, and Chrome.
I've tried implementing the suggestions made already but none of worked.

Based on your description it sounds like a firewall issue. Since you have configured lighttpd to serve static images via port 8443, you will have to make sure that you are allowing connections on that port from all clients. Since it is working from within your network it may require changes to the rules on your institution's firewall.
That was the problem. My network admin says he doesn't know why he didn't think of that .
