Problem

Support for AJP has ended in Fisheye since version 4.0, nevertheless it could still work. With Fisheye 4.7 and the upgrade of the Jetty Server to 9.4 using ajp is not only deprecated/unsupported but does not work.

Nevertheless, the option to use an AJP bind address is still present in the Fisheye UI, which is redundant and can be confusing.

Solution

Remove the option from Global Settings > Server
