Description of my issue

Hello!

This message is maybe a bit weird, because as I posted it, the problem resolved itself. I’m still posting, because maybe someone will have an explanation.

I have a Yunohost server on a VPS hosted by OVH. Now I’m moving out to another provider. I logged in in ssh on this new server, did the curl | bash thing, all clear.

Now, as I have an export of my current server, I sent it through ftp, and launched the restore action: yunohost backup restore <my_archive_name>. All is well, a bit… long but hey, not complaining here.

The problem is afterwards: I can’t login via ssh anymore. I have a timeout, even before asking for my password. I use the new port, and the admin user of the current server (“lara”). Like this: ssh -p 6789 lara@server-IP. Nothing, just a timeout.

The first time, I wiped the new server and started over. The second time, I kept a terminal window open, and the server rebooted because I tried the VNC window on my provider webpage and clicked on the “Ctrl+Alt+Del” button (yeah, I know, the joke’s on me, never click on unknown buttons). So I ragequitted.

And now I’m trying again. As I was writing, I retried to login, in order to have the exact error message to show you. And it worked. No password needed because I had a private/public key pair on the current server, which was copied in the export I guess.

So: it works. And I don’t know why. I’m a bit nervous, nevertheless. Did it happen to somebody else, who could explain?

Thank you, and long live Yunohost!
