Minecraft Dedicated server problem ?

[mahesh]

Hi ! I am currently trying to host a minecraft server , ran in a docker container on ubuntu. The server does seem to run fine because I can access it locally, but no one else can connect.. My ports are forwarded on the router, I allowed the port through ufw and enabled ufw too.. But still cannot reach it ! Is there anything in ubuntu server 20.04.2 that could prevent this ?
