Signal App can't conenct to netwokr after automatic update to version 7.2.0

Using a supported version?

[X] I have searched searched open and closed issues for duplicates.
[X] I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

After updating to 7.2.0 The Signal app was unable to connect to the network and connect to any chats. After uninstalling and redownloading latest version, the QR code won't load. Please note I am behind a proxy. Additionally, http_proxy, https_proxy are all set correctly and were working

Checking the logs, the error in both instances is due to:

SocketManager: failed to connect unauthenticated socket due to error: HTTPError: connectResource: connectFailed; code: -1 .... Caused by: Error: createProxyAgent: all=true lookup is not supported

(Please see attached logs of newly downloaded version: debuglog.txt)

Note, running curl -4 -k https://textsecure-service.whispersystems.org/ returns valid html. Conversely running curl -6 -k https://textsecure-service.whispersystems.org/ complains about being unable to resolve proxy

EDIT: Prior closed issues referred to a similar problem but did not provide any resolution, and did not seem to point to the same error as indicated by my logs.
