Describe the bug

When I started the locust server then I browse the website, the log is:

python -m locust

@lundstrj I just debugged this same error message with someone and it turned out they had a config error. They has set the worker’s master-port setting to use the WEB_UI port (8089) instead of using the expected/default bind port (5557). Not sure why this was the error in that case, but it went away when they corrected that config issue.

Same here - I just upgrade Locust + gevent to the latest version to avoid gevent issue, but the problem mentioned in this topic still exists - in my case there are 3 different messages.

+ there is something like this after the last error:
