Repository: Proxy repository to secure.central.sonatype.com site is auto-blocked

Nexus Repository 2 officially sunsetted June 30, 2025. Visit my.sonatype.com for archived documentation. Migrate to Sonatype Nexus Repository 3 as soon as possible.

The secure central service was put in place to allow SSL access to central back in a time when SSL wasn't available on the main URL. Once we added SSL to the main Maven Central site, secure.central.sonatype.com was no longer needed.

Because of this, the https://secure.central.sonatype.com URL was deprecated ub August 2014, and has been redirecting to https://repo1.maven.org/maven2 since early 2018.

We have now shut down the redirect, completing our deprecation of this service.

You can switch to the freely available secure central URL easily.

1. As a Nexus Repository administrator, select your secure Central repository in the Nexus Repositories list and open the Configuration tab.
2. Change the Remote Storage Location value to https://repo1.maven.org/maven2/
3. Click Save button to save your changes.
4. Disable the secure central capability. Open Administration -> Capabilities tab. If the Secure Central capability is present, click it to view its Settings. Make sure the Enabled checkbox is not checked. Save the capability.
