SSH not working after Cloudron installation

[jnovec]

Hello,

Let me ask you for a support for our Cloudron installation.

I reinstalled server to Ubuntu 22.04.
I set login only with ssh key
I changed a port for SSH to 2222
I changes PaswordAuthentification to NO

Then I installed Cloudron.

Now it is not working. It is not possible to login onto server with SSH.

Where can be the problem?
Do Cloudron setup some change to firewall or ?

@jnovec You can change the SSH port after Cloudron is installed. Because Cloudron installs it's own firewall, it assumes that port is 22 at installation time. You can change this post installation to any port by following https://docs.cloudron.io/security/#securing-ssh-access

[jnovec]

Oh. I set it to port 2222 before installation.

Can Cloudron firewall open port 2222 to be able to change this configuration now ?

Because if not open I am locked and not possible for me to connect to server now...

Many thanks in advance

@jnovec you cannot connect via 2222 anymore since it is already locked in firewall post installation. Don't know your setup but many server providers provide a web server console for exactly this situation. You can login in the console there and edit /home/yellowtent/platformdata/firewall/ports.json to white list the port. Otherwise, it's easier to just start afresh.

[jnovec]

Yeah. I know what you mean. Ok I will start afresh
With this information now it will be ok to configure from scratch.

Many thanks
