bigzengdotcom opened a new issue #326: Failed to get reconnected sender, all alpha server is down. URL: https://github.com/apache/incubator-servicecomb-saga/issues/326 i have a service named **membership-service** with the following interface method,just as what demo did: @ApiOperation(value="addStaff", notes="", produces = MediaType.APPLICATION_JSON_UTF8_VALUE) @PostMapping(value = "/staff", produces = "application/json;charset=UTF-8") public BaseResult<?> addStaff(@ApiParam @RequestBody StaffFormDTO staffFormDTO) { //here to invoke a method with compensatable annoation in class StaffService staffService.save(staff); } **and here is the StaffService:** @Transactional(readOnly = false) @Compensable(compensationMethod="cancelSave") public void save(Staff staff) { //ok just a demo for save staff dao.save(staff) } public void cancelSave(Staff staff){ System.out.println("cancelSave Staff ："); } membership-service is running on my local machine while the alpha service is running on a cloud server with a IP like 139.159.251.88 , logs in the alpha service shows that membership-service is connected successfullly to alpha service. when trying to run saga transaction by invoke addStaff method using post ,exception occurs as follow:
