What do I do if my request for on-premises and cloud connection is rejected? - Enterprise Distributed Application Service

This topic provides the solutions in scenarios where your request for on-premises and cloud connection is rejected.

Note

Alibaba Cloud Toolkit V2020.9.1 and later provide the quick diagnosis feature for on-premises and cloud connection. You can troubleshoot issues such as etrans channel startup exceptions and service connection failures based on the diagnosis results. We recommend that you use Alibaba Cloud Toolkit V2020.9.1 or later.

Problem description

When you initiate an on-premises and cloud connection request, the service registry rejects the request and returns the following error message:

code:403,msg: access denied

Causes

The service registry uses timestamps to ensure the security of service registration. If the time of the on-premises system is not valid, the service registry in the cloud rejects requests for on-premises and cloud connection.

Solutions

Calibrate the on-premises system time and try again.

Can I interconnect on-premises applications with cloud components?

Yes, you can interconnect on-premises applications with cloud components by using only Alibaba Cloud Toolkit V2020.9.1 or later. Therefore, you must update your Alibaba Cloud Toolkit to V2020.9.1 or later. This ensures that all the requests that are initiated by on-premises applications to be forwarded by a jump server to Spring Cloud Gateway, databases, Redis, and message components in the cloud.
