For some reason I can't log in to my xmpp server from any account other than my admin account. The client says that registration is only through invitation.

Preferably in a cheap or average price segment. thanks.

You may have noticed a few of my posts here, I am very interested in self-hosting and what advice can you give to a newbie? maybe some literature, video, I don’t know~

Hello everyone,

I've been trying to set up a Mumble voice chat server on my home network using a Debian server. As part of the setup process, I need to obtain an SSL certificate from Let's Encrypt for secure HTTPS access to the server. However, I'm encountering an error when running the Certbot client to request the certificate.

Here's the command I'm running:

sudo certbot certonly -d mydomain.com

But I get the following error message:

Timeout during connect (likely firewall problem)

I've checked my firewall rules and confirmed that I've opened port 80 as required for the Let's Encrypt verification process. Here's the relevant rule in my ufw configuration:

80/tcp ALLOW Anywhere

Despite this, I'm still getting the timeout error. Has anyone else encountered this issue before? What steps should I take to troubleshoot further?

Thanks in advance for any advice!

I have a question about the userdata size item. I set it to 5GB, as I saw in one of the videos. However, I discovered that 16GB in total is available. So what does this affect? Is it possible to use this system fully? That is, does it have any restrictions? And what if I want to reflash it again, or delete this firmware? Is it possible to place several at once? And how many?
