Several moments:

  1. You can’t join dedicated server from your computer if you launched it on your computer (same IP)
  2. If you published in the cloud, computer firewall can be blocking port (eg Windows Server does it, Ubuntu doesn’t do such things)
  3. If you published your server on AWS, they have a cloud side firewall (on top layer comparing to computer one) known as Security Groups, blocking 7777 by default surely. This can apply to other hostings
  4. If you are using docker, make sure you set up udp port forwarding correctly (standard default port forwarding is for tcp): UE4 Dedicated Server + Docker: can't set up port forwarding
