since few days, we’ve got an issue when starting nexus service

we’ve got a lot of issue trying to access to

[Central Repository: org/sonatype/nexus/assemblies](https://repo1.maven.org/maven2/org/sonatype/nexus/assemblies/)…

first error like this look like that :

```auto
2024-07-17 09:07:03,506+0200 WARN  [FelixStartLevel]  *SYSTEM org.ops4j.pax.url.mvn.internal.AetherBasedResolver - Error resolving artifact org.sonatype.nexus.assemblies:nexus-startup-feature:xml:features:3.41.0-01: [Could not transfer artifact org.sonatype.nexus.assemblies:nexus-startup-feature:xml:features:3.41.0-01 from/to central (https://repo1.maven.org/maven2/): transfer failed for https://repo1.maven.org/maven2/org/sonatype/nexus/assemblies/nexus-startup-feature/3.41.0-01/nexus-startup-feature-3.41.0-01-features.xml] java.io.IOException: Error resolving artifact org.sonatype.nexus.assemblies:nexus-startup-feature:xml:features:3.41.0-01: [Could not transfer artifact org.sonatype.nexus.assemblies:nexus-startup-feature:xml:features:3.41.0-01 from/to central (https://repo1.maven.org/maven2/): transfer failed for https://repo1.maven.org/maven2/org/sonatype/nexus/assemblies/nexus-startup-feature/3.41.0-01/nexus-startup-feature-3.41.0-01-features.xml] ...
```

in my view, there is no change on network or proxy settings

Many thanks for your helps

the error come from that the etc/karaf/org.ops4j.pax.url.mvn.cfg file was empty

we take a backup one and service came back

I believe this issue was fixed in a later version, you may wish to upgrade.
