User Peng reported that he couldn’t login to his self-hosted DB. He is running Linux/Ubuntu, which is not a supported environment. Regardless, the server is running and he provided a link to it. Looking at his emails, he is trying to used the download login/password that was provided to him. Obviously, this won’y work.
I read through the install guide and learned that he needed to use “master” and “build,” the default for a new install. I connected to his server and verified that this login worked.
