> πŸ™‹β€β™‚οΈ **katkat\_** _asked_ ## Hi everyone, I am having issues deploying this app using docker. I have my ports like this: -p 8484:8080 and 8484 is allowed on the firewall (this is an ubuntu server with nginx). Let’s say I do $ curl -I localhost:8484, I get (56) Recv failure: Connection reset by peer error. I am not very good with docker and I am not sure what I am doing wrong in terms of the networking here. Does anyone have an idea how to fix this? #### Thanks! ---
