certificate issue

[sljuka]

Hi, thanks for the plugin. When trying to add bun I get the following error:

$ vfox add bun                                                                                                   ~
Fetching bun manifest... 
fetch manifest error: Get "https://vfox-plugins.lhan.me/bun.json": tls: failed to verify certificate: x509: “self-sign.com” certificate is not standards compliant
$  

I'm not sure how the plugin is being hosted but it seems like there is an issue with its certificate.
