Slate 7 does not connect to Mullvad

Hi everyone - I am having trouble setting up Mullvad on the Slate 7. I tried different ways, but it still doesn’t work. Every time I attempt the setup, I get the error: “download the configuration failed [200001107]”.

I also set up the Encrypted DNS option.

If anyone has seen this before or knows what I might need to check, I’d really appreciate your help.

Thanks in advance.
