seeing too much error: context deadline exceeded

[BaiShaoqi]

Recently have seen a lot of error which has not seen before.

API token request failed: Post "https://network.tanzu.vmware.com/api/v2/authentication/access_tokens": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

Is there a workaround for the failure ?
for https://github.com/pivotal-cf/go-pivnet/blob/master/pivnet.go#L125
should it be larger from 60 seconds to 360 seconds ?
