API not found when accessing from localhost

Sonatype Nexus Repository

Hi,

We have a straightforward Nexus Repo 3 running behind our firewall with a reverse proxy in front for access:

Internet (443) > Reverse Proxy > Nexus (8081)

When we access the following API we can retrieve the results:
https://domain.com/v2/[slug]/tags/list

However, when we try to access the same link locally we receive a 404 not found error:
http://localhost:8081/v2/[slug]/tags/list

I can confirm that server settings are:
application-port=8081
application-host=0.0.0.0

Any ideas what could be wrong?

Nexus doesn’t have an API at /

I can only assume your reverse proxy is translating the api urls. Normally an api call starts with something like /service/rest/v1.
