Hello,
I've been trying to get mullvad to work on my kali linux 2017.3 distro for ages and as of yet nothing works. I install it and it works at first but after I've disconnected it it never works again. I've tried what seems like every command under the sun to fix this but I still have the same problem.
I surely can't be the only one who's tried to install a VPN on kali...

Are there any possible solutions to this?

I haven't altered my kali distro in any other way. It's exactly the same as any other unaltered version. There aren't any other details to submit. I have the standard kali linux OS with no changes.
