When running Jenkins with Blue Ocean UI behind an Nginx reverse proxy, the job summary page and the running job page do not always get updated correctly.   You have to refresh the web page in order to have the latest information from the job.

Attachment job1 it what I see for several minutes, but it never refreshed the page.  I know the job is completed as it only takes 23 seconds to run.  When I refresh the page, I correctly see the status (attachment job2).   Page updates do every once in a while seem to work for a job run.

When I connect directly to the backend Jenkins app bypassing Nginx, the Blue Ocean UI works 100% as expected.

Nginx is configured using the configuration file referenced by the Blue Ocean plugin here:

Only change was to change the "server_name" line.
