Cloudron Forum

For all apps which do not use the default storage but a local ext4 volume, the File Manager shows no contents of /app/data. In the browser console I find a 404 response for fetching following URL.

https://my.<domain>/api/v1/apps/cb4e9ec7-8612-41af-bcb7-eba8ef4eec23/files//?access_token=-REDACTED-

For apps with the default stroage location (/home/yellowtent/appsdata/) the File Manager works fine.

I'm currently looking for such a feature. We want to block any request to applications as a security measurement. It would hinder any unauthenticated request to any resource which would create a significant barrier for any application which is not supposed to be publicly accessible.
No request would reach the application if the client does not have a valid Cloudron SSO token.

Nice and practical feature on top of that: create an allow-list for resources or path-patterns which may be excluded from the proxyAuth requirement. This would allow us to selectively publish certain parts of an application.

Thanks for your reply. I understand, that you are not providing support for my custom system environment.
Thus our hardening modifications follow best practice (https://www.cisecurity.org/benchmark/ubuntu_linux -- "Ensure default user umask is 027 or more restrictive")
Anyhow, I think taking care of the UMASK for the cloudron system itself and the managed applications could hardly be a bad thing. You may consider it as an improvement.

Thanks anyway. Looking forward to having a good time using cloudron on our server.

Hello!
I tried to install cloudron on a Ubuntu 24.04 machine with some security-hardened aspects. One of them being running shell-sessions under a umask of 0027.
The installation process got stuck at "Waiting for cloudron to be ready". I checked the service "box.service" and found following error preventing it from starting:

systemd[1]: Started box.service - Box.
box.js[287242]: /usr/bin/env: 'node': Permission denied
systemd[1]: box.service: Main process exited, code=exited, status=126/n/a

Further inspection showed that the local node installation

$ sudo ls -la /usr/local/node-24.13.0/
total 532
drwxr-x---  6 root root   4096 May 23 21:53 .

drwxr-xr-x  4 1001 1001   4096 Jan 12 18:02 share

You can see that the directory /usr/local/node-24.13.0/ has the permission drwxr-x--- which is limiting the usage for other users.

I suggest to set a umask cloudron install process is expecting explicitly at the beginning of the install process.

Hello @james

@james said:

Where do you see the output of --troubleshoot include your domain?

Where I replaced it with <domain>:

[OK]    Dashboard is reachable via IPv4 (https://my.<domain>)
[OK]    Dashboard is reachable via IPv6 (https://my.<domain>)
[SKIP]  Domain expiry check — whois did not return an expiry date for <domain>

Was not able to reproduce this.

If the issue still persists, please contact support@cloudron.io so we can analyse this issue more detailed.

Thanks for your time. I finally realized that the issue appeared because of our restrictive umask - see Topic 15545 for details. And I already got the response, that I will run into more issues because of that. So - in hindsight - I'm sorry for bothering you because of our custom setup.
