Cloudron Forum

Ok I got R2 to work, needed to set the CORS rules just to be able to upload files, which the documentation seemed to only recommend for certain parts of Ente and not for the uploading functionality. I assume the Backblaze B2 issue is related to CORS as well.

Ok let me add Cloudron R2 to the list as well. I'm unable to get anything to upload with that bucket either. Any chance there is an override for those settings too the same way SMTP was handled?

Thanks, that SMTP override seems to have done the trick! I appreciate the quick response. Now to figure out why uploading photos doesn't work... any ideas on why Backblakze B2 wouldn't work? The logs in ente don't really provide a ton of info. And earlier I meant the cloudron command doesn't work on my cloudron terminal, not on my Mac directly. I tried it inside of the app terminal, the web cloudron terminal and even ssh into the device with no luck.

Hi there, yes I have setup the Last.fm integration. The error I constantly receive is:

[2026-05-26 03:12:00] production.ERROR: Directory /app/code/vendor/ezyang/htmlpurifier/library/HTMLPurifier/DefinitionCache/Serializer not writable.  {"userId":1,"exception":"[object] (ErrorException(code: 0): Directory /app/code/vendor/ezyang/htmlpurifier/library/HTMLPurifier/DefinitionCache/Serializer not writable.  at /app/code/vendor/ezyang/htmlpurifier/library/HTMLPurifier/DefinitionCache/Serializer.php:296)

Album art is not imported via the integration and I am unable to import album art manually. If I try and change the permission on this directory I am told its a read-only file system, just like the error from 2022.

I see there is a post from 2022 with a similar error, but no real resolution. Is it just accepted that Koel on Cloudron cannot use album art? I see there is some sort of permissions issue related to a read only file system. Would be great if there was some sort of notice or warning letting users know that album art is not supported on Cloudron if possible. Thanks.

I followed the instructions and did just the required S3 config before I tried creating an account, but nothing I do works.

@mrchrisjones before I spin up a new test instance to try to reproduce this, could you please respond to these questions:

• did you set up s3 compatible storage?
• And if so, which one?
• Also, is there anything in the logs that pops up when you try to register?
• what browser are you using
• if you are on a Mac, do you have Lockdown Mode enabled?
• could you share here or in a dm the domain so I can test the login flow my end?

Hi there, yes I setup Backblaze B2 storage. I am on a Mac, no lockdown mode. Only thing I notice is that it hangs on /api/users/otp but I am unable to trace the logs with the commands you shared as cloudron is not a found command. This is on a Cloudron install that's less than 24 hours old. The email is setup with an external smtp relay and sends emails with no error. In one of the Ente logs I do have access to I see the following error, looks like its hardcoded to some sort of mail server IP that I don't recognize.

I'd really like to give this a go on Cloudron but I just can't get it to install and function. When I go and create a new user account on the Ente web interface in spins on generating encryption keys for quite a while and then just says "something went wrong." Any thoughts?

Hi there, I just installed a fresh version of Memos, tested a couple of notes and suddenly they disappeared. The calendar shows I have 3 memos created today, but they do not appear in the list. I uninstalled the app, reinstalled and tried again and got the same results.

I see this entry in the logs, but I'm not sure if its related or not. Seems like a complete showstopper when trying to use the app.

Hi there, I'm having the exact same issue. Is there a version of the Cloudron installer that actually works? Kind of a discouraging sign to see these types of issues when following the official instructions.

An IPv6 issue was called out on Reddit 2 years ago related to Ubuntu 20.04 server. Is this the problem? https://www.reddit.com/r/ipv6/comments/lq7clv/ubuntu_2004_will_not_pull_dhcpv6/

If Cloudron does not support installing on local machines at home machines, please let me know so I can look for alternatives.
