Symptom & Impact

`SUSEConnect -r ` hangs or returns timeout when registering SLES 16 to SCC.

Environment & Reproduction

Reproduces on hosts that route outbound traffic through an authenticated HTTP proxy.

Root Cause Analysis

Proxy variables not exported for the root shell prevent SUSEConnect from reaching scc.suse.com.

Quick Triage

Test connectivity: `curl -v https://scc.suse.com/connect/subscriptions/status`.

Step-by-Step Diagnosis

Inspect `/var/log/SUSEConnect` and confirm `HTTP_PROXY`/`HTTPS_PROXY` are visible to the service.

Solution – Alternative Approaches

Register against a local RMT server that does not require the upstream proxy.

Verification & Acceptance Criteria

`SUSEConnect –status-text` lists the product as Registered with a valid expiry date.

Rollback Plan

Run `SUSEConnect –cleanup` to revert state if registration leaves the system half-attached.

Prevention & Hardening

Bake proxy variables into the base image and validate during cloud-init.
