调用rest api 修改群组信息报错

java.lang.RuntimeException: java.lang.RuntimeException: Some errors occurred while fetching a token by username and password .
出错的语句是：
URL changegroupByChatgroupidUrl = HTTPClientUtils.getURL(Constants.APPKEY.replace("#", "/")
                    + "/chatgroups/" + chatgroupID);
objectNode = HTTPClientUtils.sendHTTPRequest(changegroupByChatgroupidUrl, credential, dataObjectNode,HTTPMethod.METHOD_PUT);
