nimble refresh fails
Recently installed Nim on a new OS install and I cannot get nimble to download the package list via refresh.

Running `nimble refresh --verbose` results in:
```sh
     Info:  Nimble data file "/home/bit/.nimble/nimbledata2.json" has been loaded.
Downloading Official package list
     Trying https://raw.githubusercontent.com/nim-lang/packages/master/packages.json
   Warning: Could not download: Invalid argument
        ... Additional info: Try again
     Trying https://nim-lang.org/nimble/packages.json
packageinfo.nim(180)     fetchList

    Error:  Refresh failed
        ... Could not download: Invalid argument
        ... Additional info: Try again
     Info:  Nimble data file "/home/bit/.nimble/nimbledata2.json" has been saved.
```
Trying the same command again results in the same output.

I can easily download the urls nimble tries to via wget. Shouldn't be a network issue on my end, I have a typical setup.
Is there a way to do this manually for a temporary fix? Hard to use nimble without the official package list.

`nimble -v`
```
