the configured "remote" backend encountered an unexpected er

Error message

the configured "remote" backend encountered an unexpected error:

%s

What it means

The default branch of fetchWorkspace(): Workspaces.Read failed with an error that is neither context.Canceled nor tfe.ErrResourceNotFound. It is the generic 'something unexpected went wrong talking to the API' bucket, wrapping the underlying error for the caller to inspect.

Solutions

1. Retry the command — the message itself notes this is often a transient network issue.
2. Check HCP Terraform status page / TFE health for ongoing incidents.
3. Inspect the wrapped %s (the underlying error) for the HTTP status to distinguish auth (401/403) from server (5xx) from transport (TLS/DNS) failures.
4. Verify network/proxy connectivity to the configured hostname.

// Optional connectivity precheck to the hostname before operations.
func ping(ctx context.Context, hostname string) error {
    req, _ := http.NewRequestWithContext(ctx, "GET", "https://"+hostname+"/api/v2/ping", nil)
    _, err := http.DefaultClient.Do(req)
    return err
}

w, err := b.fetchWorkspace(ctx, org, name)
if err != nil && !errors.Is(err, context.Canceled) && !errors.Is(err, tfe.ErrResourceNotFound) {
    // unexpected -> caller may retry with backoff
    return err
}

When it happens

Trigger: Operation() -> fetchWorkspace() where the read errors with a network timeout, TLS error, 500/502/503 from the server, a malformed response, or an authentication error other than 404 — i.e., anything the two named cases don't catch.

Common situations: HCP Terraform / TFE partial outage or maintenance; client network blip or proxy dropping the connection; clock skew breaking TLS; go-tfe client receiving an unexpected response body; expired token returning 401 (not 404) on this code path.
