When running the Windows operating system, configure Localhost communications (127.0.0.1) between ERemoteServer and Axeda Builder. Refer to PTC knowledge article CS360255 Configure the Axeda agent for the authentication information required to log in to the Axeda Deployment Utility. Refer to PTC knowledge article CS360255 PTC recommends upgrading the Axeda Desktop Server (ADS) to Version 6.9 build 215 The Axeda agent loopback-only configuration is only available in Version 6.9.1 and above.
