If you work from a fixed IP, you could exclude your IP from rate limiting:

For a first test, I would skip rate limiting completely (just don’t use web.ratelimited.template.yml)

You might find the origin of the requests by browsing through nginx logs:

 ./launcher enter app
less /var/log/nginx/access.log
