I noticed that our Jenkins instance that is configured to use the Github plugin to manage authentication has suddenly stopped working. It seems the github login process fails, and the following url and exception is displayed:
/securityRealm/finishLogin?code=xxxxxxxxx java.io.FileNotFoundException: https://github.com/api/v2/json/organizations?access_token=xxxxxxxxxxxxxxxxxxxxxxxxx at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1434) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:234) at org.kohsuke.github.GitHub.parse(GitHub.java:307) at org.kohsuke.github.GitHub._retrieve(GitHub.java:196) at org.kohsuke.github.GitHub.retrieveWithAuth(GitHub.java:185) at org.kohsuke.github.GitHub.retrieveWithAuth(GitHub.java:177) at org.kohsuke.github.GitHub.getMyOrganizations(GitHub.java:420) at org.jenkinsci.plugins.GithubAuthenticationToken.<init>(GithubAuthenticationToken.java:77) at org.jenkinsci.plugins.GithubSecurityRealm.doFinishLogin(GithubSecurityRealm.java:312)
