Host verification fails for https://www.apis.google.com/ in spring social

[java_dude via StackOverflow]

I am encountering the same issue. My best guess. There is mismatch between HTTPs call and Certificate. This looks like more of a Google issue then Spring Social Google API issue.

Not sure how long this issue has been going on. I started working on this code yesterday.

Will open bug with Google and Spring Google Social

Filed bug with Google, and for social on Github

Finally found solution to this problem.

Downgrade HttpClient to 4.3.x. There is a bug filed and resolved marked for 4.5.x https://issues.apache.org/jira/browse/HTTPCLIENT-1613
