Keep getting 500 error when trying to create invoice.

[JustYourAverageGithubUser]

Everything was working for a while, followed the tutorial exactly and then suddenly started getting name: "StatusCodeError", statusCode: 500, message: "500 - undefined", error: undefined, options: Object, ... error

I have a key pair and the way I generate invoices is the exact same as is in the tutorial, except now instead of printing out invoice related information it just gives me this. I'd provide my code, but it quite literally is identical to that of the example on the README. I tried generating a new keypair once or twice, but that didn't seem to change anything at all.

A status code of 500 signifies a problem with the BTCPay Server backend. Can you confirm if there was any change made to the BTCPay Server instance you are connecting to?

A reinstall seemed to fix it. I think it's because my VPS IP changed, that's the only thing I can think of that happened around the time the system broke. Anyway, a reinstall fixed it.
