BLS Connection

By default, all BayesiaLab software and the Bayesia APIs connect to the Global Bayesia License Server, which is physically located at Bayesia’s corporate headquarters.
This requires your locally-installed BayesiaLab software to connect to bls1.bayesia.com on the destination port 2424, i.e., the BayesiaLab software opens a TCP/IP connection with bls1.bayesia.com:2424.

If your computer is behind a firewall, you may need to ask your IT department to define an exception to allow you to connect.
To check whether you can connect to the Global Bayesia License Server, open Command Prompt (on a Windows PC) or Terminal (on a Mac) and enter ping bls1.bayesia.com.

If a corporate firewall prevents TCP/IP connections to bls1.bayesia.com, a Local Bayesia License Server can be installed within your corporate environment.
The Local Bayesia License Server consists of a small program that runs in the background on a server to which your locally-installed BayesiaLab software and the APIs can connect.

This setup requires a one-time connection per license term, e.g., annually, to the Global Bayesia License Server to initialize the Local Bayesia License Server.
For the ongoing operation, however, no Internet connection is required on your server, and all ports can be blocked.

BayesiaLab and the Bayesia APIs always run locally on the hardware on which you installed the software, e.g., your desktop or laptop computer.
There is no provision for running BayesiaLab remotely on Bayesia's servers.
Your local BayesiaLab installation never transmits any of your data or models to the Global Bayesia License Server.
The only information sent to the Global Bayesia License Server is the user login and hashed password, the user account, and the version of BayesiaLab software currently in use.
