I have an issue where Nexus OSS cannot connect to repositories such as Maven Central and all others if I am over my Companies VPN. If I am not over VPN nexus can find and download artifacts. If over the VPN nexus cannot locate repositories. Any Ideas or suggestions, … thank you!
1. company uses a proxy script, I tried using the proxy script but I don’t think nexus supports this. it did not work.
java.net.UnknownHostException: [myapps.setpac.ge.com/pac.pac](http://myapps.setpac.ge.com/pac.pac)
org.sonatype.nexus.proxy.RemoteStorageException: Transport error while executing GET method [repositoryId=“central”, requestPath="/.index/nexus-maven-repository-index.properties", remoteUrl=“[https://repo1.maven.org/maven2/.index/nexus-maven-repository-index.properties](https://repo1.maven.org/maven2/.index/nexus-maven-repository-index.properties)”]
2. I remove the co. proxy script reference and go directly to the corp proxy server, but then I get a PKIX error.,
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
is there something I’m missing? what am I doing wrong? What did I miss?
thank you

For problem #2 have you tried trusting the certificate of the remote in the repository configuration?

rseddon,
hey, I don’t have the administrative repository sub menu as described in the doc link. maybe this is my overall problem. Why wouldn’t I have this.
" The administration user interface for repositories and repository groups is available via the _Repositories_ item in the _Repository_ sub menu of the _Administration_ menu."

I missed the fact you were running Nexus Repo 2.x in my original reply. See here:

Rseddon,
thanks so much for helping me. Rseddon, It looks like there is something missing with my Nexus Repo OSS 2.x . the suggested instructions give a SSL tab on the repository. hmmmm, I don’t have such a tab. what did I do wrong? did I miss something during installation ??

Rseddon,
I just tried to create another proxy repo to see if the SSL or Truststore option is there and it is not an option when setting up a proxy repo?

The SSL tab only shows up if the URL of the proxy uses https. What is the URL set to in the central proxy?

Sorry, I’d forgotten that in Nexus 2.x the SSL UI is a pro only feature, and requires a license. In Nexus 3.x the SSL feature is in both OSS and pro.
You’ll need to use this technique to import the certificate into the truststore of the java running Nexus:

Rseddon
it sounds like it is a licensed feature in 2.x but it comes out of box in 3.x - is this correct? if I upgraded to 3.x OSS would I need a license?

Yes, that’s right, if you upgrade to Nexus Repo 3 you don’t need a license for the SSL feature.

I will upgrade soon, but the proxy cert import worked.
