​I met the same issue recently. This cause might ​be new jenkins (>=
2.46.1) change to POST method.
Add a empty body in the request will make it use POST method which should
fix this issue:
self.server + CREATE_NODE % urlparse.urlencode(params))) ==> self.server +
CREATE_NODE % urlparse.urlencode(params), b''))
