Hello,
on OVH I only have a public cloud instance that runs nginx on ports 80 and 443, and I opened the server’s ports with ufw. I haven’t configured anything else.
As soon as I try in a browser or with the CLI curl to access http://{my-ip} or https://{my-ip}, the IP is not found and I get a timeout error.
I don’t understand—SSH finds the IP just fine. Does OVH block access to any ports other than 22?
Hello,
Which type of instance are you referring to?
https://www.ovhcloud.com/fr/public-cloud/
By clicking on Public Cloud in the top bar
https://manager.eu.ovhcloud.com/#/public-cloud/?onboarding
I selected a Discovery-type instance that includes 1 vCore, 2 GB of RAM, and an Ubuntu OS
Since you seem to be discovering the world of system administration, I recommend starting without a firewall.
First you get something that works, then you start looking at securing with a firewall.
The timeout is typical of firewall blocking, and apparently you haven’t opened the ports correctly.
I just uninstalled ufw, same problem. Should I let OVH know that I want to make my IP accessible to everyone?
No, but either you have a public IP, and in that case it works automatically.
Or you only have a private IP, and then it’s a lost cause.
cf. the question by @fritz2cat
I think I’ve identified my problem, I’m trying a new instance with my own private network.
It appears there is indeed a blockage:
nmap -p 80 -Pn 141.94.34.214
Starting Nmap 7.98 ( https://nmap.org ) at 2026-06-03 13:54 +0200
Nmap scan report for 141.94.34.214
Host is up.PORT STATE SERVICE
80/tcp filtered httpNmap done: 1 IP address (1 host up) scanned in 2.51 seconds
Everything works, I had to, when configuring my machine, specify that I want to have my own private network.
A big thank you to both of you for all the clarifications 
Thanks, that was it, I had to create my own private network so I wouldn't have a gateway (I don’t know what that is, but I think I should have configured it).
Everything works now
