[X007] Unauthorized / 503 Service Unavailable when scanning --skills in EU region (api.eu.snyk.io)

[aleixvilaseca]

When attempting to run snyk-agent-scan on a machine located in Europe using a Snyk EU Enterprise account, the scanner fails to authenticate or reach the analysis server for agent skills, even when SNYK_TOKEN and SNYK_API (or --base-url) are correctly configured.

To Reproduce

Set environment variables for EU region:

$env:SNYK_TOKEN = "eu-api-token"
$env:SNYK_API = "https://api.eu.snyk.io"

Run the scan on a local directory containing skills:

uvx snyk-agent-scan@latest scan --skills .\.github\skills\

See error:

Initial attempt (without explicit API env): [X007 info]: Could not reach analysis server: 503 - Service Unavailable

With SNYK_API set: [X007 info]: Unauthorized. Please check your SNYK_TOKEN environment variable or your push key.

uvx snyk-agent-scan@latest scan --skills .\.github\skills\
