Hi Eric. I do not have Fiddler on Linux, but did run WireShark. I am a novice with wirekshark, but did not see any errors. Treid reverse lookup of many ip addresses, but saw nothing associated with ESRI. Perhaps you are using a cloud server, can you tell me what IP address to monitor in Wireshark. I think it is still a libssl error (see output below) , even though I have treid it with libssl as installed by ubuntu 16..10 and installed lbssl and put it in /usr/local/lib and then et LD_LIBRARY_PATH to search there first.
