Some more data points: it isn't the firewall. Connecting via localhost 
is OK, connecting via external domain name or IP address is not. Small 
files (~50k) load OK, larger files (~250k) fail as follows:

org.eclipse.jetty.io.RuntimeIOException: 
org.eclipse.jetty.io.EofException: Early EOF
	at 
org.eclipse.jetty.server.Request.extractContentParameters(Request.java:548)
	at org.eclipse.jetty.server.Request.getParameters(Request.java:435)
	at org.eclipse.jetty.server.Request.getParameterMap(Request.java:1084)

(I made a couple of changes to try and get more info out of the system.)

The logfile contains entries like this:

 - - [23/May/2021:08:50:37 +0000] "POST /edit?course=XY101 HTTP/1.1" 500 0

It was previously a 302 error, now a 500, and there is no source IP 
being recorded for the request.

It presumably isn't Jetty-related, since it works from localhost, but 
perhaps someone with more knowledge of networking nuts & bolts than me 
can suggest some reason why this might be happening?
