[Ubuntu] Server not responding (FIXED)

[orchid nymph]

Hey, I think I've done every step mentioned in the PZ's wiki for setting up a server on ubuntu. It starts fine, files have been generated and I haven't noticed anything unusual in the logs.

However, after trying to connect to the server using the public IP it just prompts me "The server failed to respond" message. I've restarted the server multiple times, added all required ports, and so on without any success. I'd be grateful if someone could help me!

/edit: I'd also like to add that it's not my router port forwarding issue, as my friend also cannot connect.

@green pond help a homie in need i got the same problem 😩

Are you able to connect to it when you use your Local IP in the IP tab?

And have you tried disabling ufw as a test?

[orchid nymph]

i don't think that i am able to use local ip to connect to a server hosted on a vps, also yeah - i did try disabling ufw, but it still didn't change anything

using oracle cloud if it changes anything

[green pond]

It might, just to check, isnt Oracle cloud on ARM? Or do you have the x86 version of the VPS?

ARM is for free as far as I am aware

[orchid nymph]

it's x86, yeah

I may suggest looking through their documentation on port opening in that case

Because some hosting services have special rules for UDP ports

For example, Hetzner uses a stateless firewall so you have to define every action otherwise it is blocked. You have to allow UDP connections to the ephemeral port range (32768-65535)

I am not familiar whether Oracle has something similar, but you can try adding that range and see if that helps?
