The installation went fine, but seems for some reasons Mullvad app blocked access to all network access & cannot login using numeric credentials

hmm why not use openvpn?

nagito || Knight of Emilia•11/19/25, 8:33 PM

why bother with the app?

Nnagito || Knight of Emilia hmm why not use openvpn?

~PUPPY~OP•11/19/25, 8:34 PM

Because I've used the app on my other installs. I'm familiar with it and all I have to do is type in my 16-digit account number and it normally works

And I got it to install successfully. It's just yelling at me that I can't type in my 16-digit account number

It's saying that I'm having some sort of firewall issue

Because I already pay for this service

And this means that I don't have to retroactively generate new open VPN, tail scale or wire guard configurations

I can just select which server I want without having to manually generate new configuration files

Nnagito || Knight of Emilia why bother with the app?

~PUPPY~OP•11/19/25, 8:35 PM

It's also a major usability component like it's much more user friendly and much more accessible and much more usable

Despite my dyslexia because things that require me to generate configuration files and then go over said files

There's a huge percent chance because of my processing issues that there might be some error that I won't catch

So it just increases the chance of security issues and vulnerabilities if I have to do things using textual config files
