Server not available after reboot

SirFiChi

Hello Cloudron Team,
after a reboot of our system the Cloudron instance cannot be reached anymore.
I am also not able to log in to the Cloudron site with one of the mail addresses because the mails were managed through the Cloudron server (@OS-Television.de).
What options do I have to either get our server started Cloudron again to retrieve mails, or log in to Cloudron.io?
Thank you thanks for the support.

@SirFiChi Have you see https://docs.cloudron.io/troubleshooting/ ? Let us know the status of the server following those steps.

@girish
Expired domain - I restarted the server within the webinterface.
Nginx error - I'm not able to connect to the server since the reboot.
Failed upgrade - I'm not able to connect to the server since the reboot.
Unresponsive App- I'm not able to connect to the server since the reboot.
Unresponsive Service - I'm not able to connect to the server since the reboot.
Certificates - I'm not able to connect to the server since the reboot.
DNS - I'm not able to connect to the server since the reboot.

@SirFiChi use the VNC console from your hosting provider to access the server if SSH is not accessible.

There is nothing more we can do for you since you have no access to your server and can't provide logs/errors or anything else.

OS-Television.de seems to respond just fine.
my.OS-Television.de does not (if that is where your cloudron dashboard was installed)

Is the expired domain renewed?

subven

@robi if you ping both domains, you get different IPs which indicates that the root domain points to another server and not the one in question.

SirFiChi

@subven
Cloudron is installed on my.tvorga.de.
VNC of my provider isn't possible too. =/

But I got the Password-REset-Mail for one of the two possible Mailadresses.

I'll try to contact the provider.
Thanks for your help.

SirFiChi

Hello together,
The current status is that I found out that you can access the installation from the rescue system via chroot, and that the SSH port on Cloudron is not 22.
So now I can say that SSH works. I have reset the root password, but it asks for a "verification code".
The installation is still not accessible via https/http.

Can I set the "Verification code"?

subven

@SirFiChi the root password can only be set by your VPS provider. It has nothing to do with Cloudron. I guess by "verification code", your VPS provider is asking you for a code to verify that you have access to the mail address associated with your VPS account. This is to prevent intruders from taking over everything after a login is compromised. AFAIK, non of your current problems are Cloudron related.

The standard SSH port for Cloudron is indeed 22 but can be changed by the server administrator (you).

If you want to change the password for a Cloudron account, you can do so over SSH.

SirFiChi

@subven
All these professionals around me.
Thanks for the tips. I had GoogleAuthenticator installed, but no longer have the appropriate app on my phone (due to phone swap). I was able to restore access now and the nginx must have a broken configuration?

@SirFiChi

There is your error

Nov 17 23:43:18 vmd52314.contaboserver.net nginx[879]: nginx: [emerg] cannot load certificate "/home/yellowtent/platformdata/nginx/cert/old.os-television.de.cert": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/home/yellowtent/platformdata/nginx/cert/old.os-television.de.cert','r') error:2006D080:BIO routines:BIO_new_file:no such file)

I would suggest to copy an existend certificate from this folder and rename it to old.os-television.de.cert. I guess the app behind that URL was stopped (for a while)? In this case, Cloudron had(?) a bug where certs for stopped apps did not get renewal and could lead to the sitauation where NGINX does not come up after a restart.

After you are able to restart NGINX and bring up your Dashboard, you should start the stopped apps and renew their certificates. You can delete the fake old.os-television.de.cert we just created from the filesystem right before you trigger a certificate renew so it will be renewed 100% with a correct cert file.

Apache2 is not installed, but there are processes running for Apache2 with paths that are not present.

Ahhh, but the cloudron-site is available. I try to fix the certificate...

Hope you did not made the mistake to manually install packages on the server or do stuff like apt update/upgrade. Use systemctl restart box to restart Cloudrons services only. I also like systemctl list-units --failed

@subven
I did this about 2-3 hours ago in recovery mode.... -.-

@subven @girish @robi
Thank you for the renewed competent help and patience.
After I had restored the last backup, the old instance could be restarted and stopped.
After a reboot of the server everything runs as usual again.
I hope my system has now no lasting damage by apt-get update/upgrade/dist-upgrade and "apt autoremove".

I hope so too but to be sure you can make a backup and restore on a fresh and clean installed Ubuntu 20.04 (or whatever you're currently using). Just make sure to restore to the same OS and Cloudron version and you should be fine. There are also guides what to do after a (planned) dist-upgrade so maybe check them out.

Cloudron makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server. Find out more or install now.
