Error message

resp.Errmsg

What it means

Thrown by the yunpan360 Open API authentication flow when the auth endpoint responds with a non-zero Errno. The server's Errmsg is returned as-is; this error means the driver could not obtain an AccessToken/Qid/Token triple, so all subsequent Open-API calls will fail.

Solutions

1. Re-enter or refresh the Open API token/credentials in the storage config
2. Confirm the token belongs to the correct 360 Open app and account (SubChannel matches)
3. Check the errno value accompanying the auth failure — relogin-type errnos mean the stored token is dead and must be re-issued
4. If auth keeps failing right after success, verify server clock and credential formatting

Example fix

// before
return nil, errors.New(resp.Errmsg)

// after: keep errno context
return nil, fmt.Errorf("yunpan auth failed: errno=%d: %s", resp.Errno, resp.Errmsg)

if strings.TrimSpace(d.Addition.Token) == "" { return errs.EmptyToken }

func isAuthErr(err error) bool { return err != nil && (strings.Contains(err.Error(), "yunpan auth failed") || strings.Contains(err.Error(), "errno=")) }

auth, err := d.openAuth(ctx)
if err != nil {
    // clear 50-min cache so next call re-authenticates
    d.openAuthExpire = time.Time{}
    auth, err = d.openAuth(ctx)
    if err != nil { return nil, err }
}

When it happens

Trigger: Calling the Open auth endpoint (OpenAuthResp decode in drivers/yunpan360/util.go:213) with an invalid/expired app token, wrong SubChannel, malformed credentials, or when the 360 Open platform rejects the sign-in. Any operation that triggers d.openAuth() (listing, upload, download via Open API) can surface it.

Common situations: Expired Open API token past the 50-minute cache window with refresh rejected; credentials copied incorrectly (trailing whitespace, wrong app key); the 360 Open platform account hit a quota or was disabled; clock skew breaking signed requests.
