I have a Jenkins server on my local machine that I publish to the outside world through a DNS A record (ci.alanif.se:8080) with my ISP and port forwarding through two routers.
This works perfectly fine from the outside and from any machine on my local network except my local machine, where a browser typically says:
Server did not send any data (ERR_EMPTY_RESPONSE)
Why is this and how can I fix it?
