Disconnected: No supported authentication methods available (server sent: publickey)

[Dreamcatch22]

Hello,

I was upgrading my server on AWS from ubuntu 20 to 22.

I followed this guide: https://docs.cloudron.io/guides/upgrade-ubuntu-22/

I created a snapshot and proceeded with the upgrade. Everything worked! But I have run into some issues:

• But I can no longer SSH into my server using putty. I keep getting the error "Disconnected: No supported authentication methods available (server sent: publickey)"
• One of my wordpress apps has become unresponsive and throwing up an error.

Any ideas or suggestions on what I can do to fix this roadblock I'm facing?

@girish Is there a ticketing system for support/help for cloudron users who are paying? Or is this forum the best way to ask for help?

Thank you!

@Dreamcatch22 SSH using the public key you made during installation (either while installing cloudron or the OS you may have made one as the server is asking for it).

Cloudron doesn't manage SSH key access. As @murgero said, this is the key that you put at installation time.

@girish Is there a ticketing system for support/help for cloudron users who are paying? Or is this forum the best way to ask for help?

The forum is the best place for the first line of support. If we cannot sort things out here or something is really urgent you can always mail support@cloudron.io . (email support has no special priority over getting answering on forum though...)

One of my wordpress apps has become unresponsive and throwing up an error.

can you post the logs of the app? that should give an idea why it's not responding.

Thank you everyone for taking the time out to respond to us.

@murgero I was using the same key. Nothing changed. All I did was follow the instructions to upgrade from 20 to 22. That was the weird part. Why did SSH access change or permission change for the virtual machine?

@joseph Appreciate the follow-up. I had to use the snapshot to recover everything. Ill try the upgrade later and see if it works. Maybe i just had a weird issue and a package messed up.

But here was the error I was getting from the unresponsive wordpress app:

Inactive - Error getting IP of redis-3e2e5aad-1513-4b65-bb24-5eaafc998daa service

The app was also not able to go into repair mode.

Services -> Redis -> Restart . Then, try the repair. Think it should work after that.
