Nuget hosted repository wrong index.json for some packages

[Mariska]

Hi,

We have a hosted nuget repository in our nxrm3 instance that is accessed via a reverse proxy.

In short:

https://nexus-external-url -> http://nexus-internal-url

The nexus-internal-url is not accessible directly, only from the reverse proxy.

For unknown reason, there is one nuget package (all package versions are affected) that shows the internal url in the package id instead of the external url. I can see that in the https://nexus-external-url/repository/nuget-hosted/v3/registration/5/package-x/index.json.

When teams try to download the package via 'nuget install', they get an error message:

```

PS C:\> nuget install PackageX -version 2.24.0 -source https://nexus-external-url/repository/nuget-hosted/index.json

```

The https://nexus-external-url/repository/nuget-hosted/v3/registration/5/packagex/index.json registry shows:

```

"count":1,"items":[{"count":12,"lower":"2.17.0","upper":"2.25.0-alpha0013","parent":"http://nexus-internal-url/repository/nuget-hosted/v3/registration/packagex/index.json","@id":"http://nexus-internal-url/repository/nuget-hosted/v3/registration/packagex/index.json#page/2.17.0/2.25.0-alpha0013","items":[.....]

```

I've tried rebuilding the index, but the index.json doesn't change.

Anyone knows how to fix this? It doesn't seem right that those package id's are hardcoded in the index.

Strange thing is that for most packages the id does point to the external nexus url.

Any help is greatly appreciated. I came across this thread https://community.sonatype.com/t/nexus-nuget-v3-repo-behind-reverse-proxy/5263/10, but can't find a solution how to recreate the index.json.

Note: we are running Nexus OSS 3.65.0-02.

Kind regards,

Mariska.
