Request updates.jenkins.io failed

Using Jenkins Ask a question
1

where I build a jenkins image, I use jenkins-plugin-cli to install plugins automatically.
Then it reports this problem:
exception (org.apache.http.NoHttpResponseException) caught when processing request to {s}->https://updates.jenkins.io:443: The target server failed to respond

I ping updates.jenkins.io, ip is 52.202.51.185, but 100% packet loss.

Is the service normal?

2

Yes, the service is operating normally. The IOException and automatic retry is performed by the plugin installation manager tool because the Apache web server hosting that site is sometimes overloaded and requires a retry. The Jenkins infrastructure team is moving that service but is being intentionally careful with the testing and verification of the replacement before deploying it.

More information about the transition is available in the help desk ticket describing the move of updates.jenkins.io

4

is there a mirror service can replace updates.jenkins.io ?

5

Yes and no. There is a plan in process to move updates.jenkins.io to a different mirror configuration.
