running Jenkins through a reverse proxy and see the "It appears that your reverse proxy set up is broken." All troubleshooting came up with no issues in configuration. Ran getTestForReverseProxySetup in Groovy console and saw NullPointerException.
This will reproduce it every time:
import hudson.diagnosis.ReverseProxySetupMonitor;
def monitor = new ReverseProxySetupMonitor();
def testResult = monitor.getTestForReverseProxySetup();
First part of output and error message is:
java.lang.NullPointerException: Cannot invoke "String.startsWith(String)" because "rest" is null at hudson.diagnosis.ReverseProxySetupMonitor.getTestForReverseProxySetup(ReverseProxySetupMonitor.java:99) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) at java.base/java.lang.reflect.Method.invoke(Method.java:580)
