I've tried to stick a friend twice with different stickers. Each time got this error message:

Fatal error: Uncaught exception 'GuzzleHttpRingExceptionConnectException' with message 'cURL error 7: Failed to connect to livethings.subeta.net port 5001: Connection refused' in /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/CurlFactory.php:126 Stack trace: /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/CurlFactory.php(91): GuzzleHttpRingClientCurlFactory::createErrorResponse(Array, Array, Array) /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/CurlHandler.php(96): GuzzleHttpRingClientCurlFactory::createResponse(Array, Array, Array, Array, Resource id ) /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/CurlHandler.php(68): GuzzleHttpRingClientCurlHandler->_invokeAsArray(Array) /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/Middleware.php(54): GuzzleHttpRingClientCurlHandler->__invoke(Array) /www/subeta.net/vendor/guzzlehttp/ringphp/src/Client/Middleware.php(30): GuzzleHttpRingClientMiddleware::GuzzleHttpRingClient{closure}(Array) /www/subeta.net/vendor/guz in /www/subeta.net/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php on line 49

The sticker didn't stick but also vanished from my inventory
