Using proxy_ssl_verify getting error: upstream SSL certificate verify error: (20:unable to get local issuer certificate)

[justink101]

Setting:

proxy_ssl_verify_depth 2;

Fixed the issue. Can somebody explain why this is needed and why the default
setting is 1? I am using a standard wildcard SSL certificate from GoDaddy.

Thanks
