I am using a global proxy as described in Run an NGINX proxy on Fly · Fly. My origin server is hosted on Heroku
I am intermittently seeing a 302 redirect to http://[my domain]:8080/security/login. The requests causing 302 redirects are not hitting my origin server at all. (1. there are no entries in the heroku router logs 2. the via ‘1.1 vegur’ header is missing)
Any idea why this is happening? What am I missing here?
