Cloudron Forum

@joseph Many thanks for the clear and detailed explanation!

Hi, I’d like to ask a question about the Firewall. What is the function of the Firewall in Cloudron?

For example, if an IP is blocked in the firewall, does it automatically prevent access to all applications installed on Cloudron?

Additionally, if someone attempts to access the SSH server and gets blocked by Fail2Ban, can we automatically add that IP address to Cloudron’s firewall?

I appreciate your time and attention.
Thank you.
Best regards.

Is there any compatible issue with Ubuntu Pro and Cloudron if I enable this feature? Currently I am using Ubuntu 24.04.1 LTS.

@joseph I think the problem came from my SMTP provider.

  "message": "Message Queued (BD37BA83-C51B-465E-BB2F-9AF424226800.1)"
}

After change the SMTP using the default server, the problem is solved.

@girish My question is: does the "Sync DNS" feature only disable IPv4, requiring manual deactivation of Cloudflare's proxy for IPv6? In my case, for both the VPN application and my.cloudron.domain, I had to manually disable Cloudflare’s proxy for IPv6.

@nebulon yes, I am using ipv6 enable on my server. I think some app like VPN and my.cloudron.domain in my case didn't sync properly. It's only IPv4 that's not proxied with Cloudflare, the IPv6 still proxied with CF.

I discovered a conflict between Cloudron and Cloudflare when clicking the "Sync DNS" button.

Upon clicking it, I checked the DNS settings on Cloudflare and found that the domain my.cloudron.domain, which is not proxied, only uses IPv4 while IPv6 is still being proxied by Cloudflare. As a result, some services, such as email, are not functioning properly.

Moreover, not only is the my.cloudron.domain affected, but applications like the VPN on Cloudron are also using Cloudflare's proxy for IPv6, causing the VPN service to fail. Is this considered a bug?

I hope this information proves useful to others as well.

Thank you.
Regards.

@p44 In the previous setup, I used mailketing SMTP server, after using the Built-in SMTP server. I can send emails to several email addresses simultaneously.

I'd like to confirm that the problem was coming from my 3rd party email relay service. I just disabled it and using my own server without having problem at all.

Dear Cloudron Team,

Today, I conducted a test by sending emails simultaneously to multiple addresses such as @gmail.com, @outlook.com, and others. However, when I sent the email via Cloudron’s system, only the first email was successfully received, while the rest did not receive the message.

I then attempted a second test using “reply to all,” but the result was the same—only the first email received the message, and the others did not.

My question is: Is there an error in my server configuration, or is there a bug in Cloudron version v8.2.4? I have tried disabling IPv6 and syncing again, but the result remains unchanged. I also attempted enabling both IPv6 and IPv4 simultaneously, yet the issue persists.

Could you please advise on what steps I should take to resolve this issue?

Thank you for your attention and assistance.
Regards

I got it, I will contact them for this issue. Thank ou @joseph

I have a server hosted on Netcup, which already includes IPv4 and IPv6.

However, I’ve noticed that Cloudron cannot detect my public IPv6 address.

Some information might be helpful:

root@account# host -t AAAA ipv6.api.cloudron.io
ipv6.api.cloudron.io has IPv6 address 2604:a880:800:10::b66:f001

root@account# curl -6 https://ipv6.api.cloudron.io/api/v1/helper/public_ip
curl: (7) Failed to connect to ipv6.api.cloudron.io port 443 after 1 ms: Couldn't connect to server

Could you help me resolve this issue, please?

Thank you.

Thank you the problem is solved.

@joseph I try this command

su yellowtent

But when I used password for the root, it failed. How to know the password of yellowtent user?

@joseph I try to create a new folder (/custom_pages) using SFTP but it show that permission is denied.

I just saw this folder path

/home/yellowtent/boxdata/

Should I create new folder for /custom_pages/ ?

After migrated to new server, I just accessed the IP address and I found a message like this :

You cannot view Cloudron dashboard by IP address. Instead, navigate to the domain you configured during setup i.e https://my.domain.example .
If you do not remember your domain, SSH into your server and run cloudron-support --owner-login .

Is it possible to redirect when someone want to access the IP Address of server and he will redirect to https://my.domain.example, instead of see the message above?

Thank you.

My problem is solved now using this command:

sudo lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv  
sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv              

Thank you DeepSeek hehe

Dear Cloudron Team,

I recently attempted to set up a dedicated server with 512GB of storage.

However, during the server migration process, I noticed that the Disk Usage section only shows 105.09GB available. It seems there might be a misconfiguration on my part.

Could you guide me on how to ensure that the full 512GB of my server is fully utilized by the Cloudron system? Below are some details I can share for your reference:

Thank you for your assistance.

@nebulon I see the log file on Storage/Logs

I already deleted the previous file, which was almost 300MB.

@joseph Thank you, it works now! cc: @nebulon
