I tried running conda from a command prompt, and it resulted in the following, which suggests that it is trying to connect to the internet. In my workplace there is no direct internet access and browsers must use a proxy server. Perhaps ArcGIS's conda does not respect the environment's internet connection settings? In addition, these messages did not appear in the conda_debug.log file.
