I’ve been using Surfshark for over 8 years and don’t have any trouble like you mentioned. Then again, I have an ISP (Freedom Internet) I trust more than my VPN (even though i’ve not read anything bad about them) and use Surfshark only for region checks and torrenting on my NAS. I love the apps (for great on all platforms), speed and lots of exit points to choose from.

Maybe you can drill a whole from the outside just enough to view the trace and the copper peg, solder it together through the whole and then close the hole up with a plastic patch and glue. It won’t be the prettiest fix, but soldering seems like a much better connection the this.

And this looks like a real engineers mistake to have such high current flow through such a flawed connection. Be safe though! Test a couple of times before trusting the machine again.
