When I run server as docker container, statistics update correctly. Probably works properly on Linux and on Windows not.

I believe I am having this problem on my server too (1.21.4 Fabric).

When you stop the profiler with /spark profiler stop, does the page differ at all from the live view provided before? For me, the information at the top of the page gets updated after stopping but the graph, and all other profiler information, appears unchanged.

The profiler appears to work as long as /spark profiler open never gets executed. Nothing ever gets logged after the live viewer is opened.
