Nginx proxy stopping live update of ssl scan

[ghost]

Using nginx in front for SSL termination and proxy to the docker on 8080. The SSL scan completes and report generated, but the dynamic updating of progress output does not work. Would there be specific nginx proxy settings needed to get the repeat POSTS to /tools/testssl working?
