Cannot connect to Moonraker (after Moonraker Update?)
Hello Together
Just wanted to start the printer today. But now I have an error: "Cannot connect to Moonraker".
Probably after the last update...
Is there a known solution here?

Your moonraker.log just stops abruptly. There's no telling what went wrong, there are no fatal errors. Did you try rebooting your pi?

Thanks for your feedback.
I have restarted the printer several times and plugged and unplugged it.
I think I had run the updates two days ago. but then not used the printer since.
Could it be this update that is not working?
No, checked that, works fine
Might be SD card corruption.
Or you ran out of space or something
Hard to tell without more information.
ssh in to the pi

Yep, SD card corruption
I'd get a new SD card and reinstall
(i know that sucks to hear)
you can get the contents of your current config files through ssh
for example run
stormy-gold•16mo ago
I have access via filezilla.
So I can copy everything
seems like you installed a few moonraker extensions and modified your moonraker config, get that via:
Ok great! that'll work fine 🙂
I recommend sandisk extreme for the sd card btw
(if you're going to buy a new one that is)
stormy-gold•16mo ago
is there a way to test if it is possible to reinstall Moonraker via ssh command to test if it works after all?
You can try that, but it's only a matter of time before something else gets corrupted and cause erratic behavior
just a sec
stormy-gold•16mo ago
It works!!! (Temporary)
Thanks for your super help!!!
You're welcome 🙂
