@Mantas: Thomas from Yaler here. In order to access the debug service via Yaler you’ll have to set up an additional YalerTunnel for localhost:2000 using a separate relay domain. If the client does not support HTTP proxies, you’ll also need a YalerTunnel instance on your client. All this will only work if the debugging protocol is TCP-based. Feel free to contact me directly by email (see https://yaler.net/help).
