Describe your issue:

I tried to upload a Gcode using Cura, but it wouldn’t connect. I then tried to SSH into it, couldn’t connect. I still have access through Mainsail and Klipperscreen, and have full conrtol, but that’s it. I’m not sure what has happened or why it’s doing this. What would be a good way to start fixing this?

I’m not sure what you are reporting here.
According to the log, everything is correct on the Klipper side.

Not being able to SSH into the RPi is far to unspecific to offer any help and in addition there are more than enough guides available how to work with SSH.

The Cura plugin for direct upload can be finicky. Settings need to look like:

Thank you for the reply. This is the error i get with Cura:
Also this is the response i get from trying to SSH into it:
This is the response i get from trying to update Klipper from Mainsail:

Let me know if theres any other info you need. Ill do my best to get it to you. I have two Ender 3s that run Klipper, both on separate Pi’s, but one doesnt seem to want to work.

Do you have SSH enabled in the Pi?

Yes, it just start not allowing me access today. It’s been set up and running fine for a few weeks now, just ran into this issue today.

Almost impossible to diagnose from remote.
Seems to be an issue with the Linux OS and / or the RPi hardware, or even on the side of your router.

I’d try setting up a new SD card and booting the RPi with it.

Will that erase all my config files on that Pi? Or will it be good?
