Why is my on-premises and cloud connection request rejected with a 403 error?
Symptom
When you initiate an on-premises and cloud connection request, the service registry rejects the request and returns the following error:
code:403,msg: access deniedCause
The service registry uses timestamps to validate service registration requests. If the clock on your on-premises system is out of sync with the cloud, the service registry rejects the connection.
Resolution
Synchronize your on-premises system clock with a reliable time source, such as an NTP server, and retry the connection.
Alibaba Cloud Toolkit V2020.9.1 and later include a quick diagnosis feature that detects issues such as etrans channel startup exceptions and service connection failures. Upgrade to V2020.9.1 or later for built-in diagnostics.
Can on-premises applications connect to cloud components?
Yes, but only with Alibaba Cloud Toolkit V2020.9.1 or later. Requests from on-premises applications are forwarded through a jump server to the following cloud components:
Spring Cloud Gateway
Databases
Redis
Message components
Upgrade Alibaba Cloud Toolkit to V2020.9.1 or later to use this feature.
