I don’t know about the UX, but if you want peoples to use your app, it need to look nice.

If only it didn’t looked like a 20 year old software.

When you are bored, backup a VM then hard kill it and see if it manage to restart properly.
Software should be able to recover from that.
If it doesn’t, troubleshoot.

Reading the title without seeing the category name …

Where I live, for 45€ you get 800GB, not 8TB :').

Can you ping an IP instead ?

Configuration looks correct, it doesnt work ?
Mind that the ipinfo also fails on my end, but torrenting works.
There are websites to test if your torrent is using a VPN or not.

Which command did you write to get the config file ? I remember that I did a mistake on it.

They want you to install their client, but it’s wireguard under the hood, so you can make it work with glutun.
You need to generate a wireguard config file with this tool: https://github.com/ViRb3/wgcf
There is a bug with gluten which make it not accept nameservers for a custom wireguard config: https://github.com/qdm12/gluetun/issues/2042
So you will need to resolve the IP yourself.
Personally, I set it up through TrueNAS, and I didn’t managed to make it work with a file config, so I passed everything through environment variables.
Use this wiki if you are lost: https://github.com/qdm12/gluetun-wiki/blob/main/setup/providers/custom.md#wireguard
It output in USA for me, it torrent with a very decent speed, 150-200/Mbps.
And yes, it’s free.

Cloudflare warp VPN does that.

You just made a mistake into saying what domain name you will take, someone may buy it before you in order to extort money from you.
It probably won’t happen but…

It’s a few euro per year, plus you can mutualize the cost with your family, take a domain name with your last name, this will allow your whole family to have firstname@lastname.yourcountrytld.
I just looked for my lastname, it’s around $10 per year.
I’ll repeat this again, but it means you will own this domain name, you have legal ressources and big companies won’t be able to take your mail address from you.
Else, use duckdns if you really don’t want to pay anything.

I don’t know, maybe ?
But I recommand strongly to have your own domain name.
As long as you do nothing illegal, when you own a domain name, you have legal recourse to keep it. It’s not the case for an email service mail like gmail, which can ban you for no reason tomorrow, and you have no recourse to get back your email address back.

I recommend duckdns instead, which is more well known in the DIY community. It’s also a dyndns like other told you to use.

The thermal dissipation is directly linked to the amount of power consumed.

I just bought a cheap Intel i3 10100T that have a TDP of 35W.
There is a bios option to reduce that to 25W.
Thoses are not sold to end users and must be purchased through craiglist or equivalent.

Missed KVM, IPMI, VM, at least.
