This is the only one which worked on the local machine with also invalid SSL certificate from all the tried ones from the "Chrome Web Store". While others had just been throwing internal code exceptions without any explicit meaning, this one showed an actually meaningful error message and helped in resolving the initial server-side issue. Sincere appreciation, and additional gratitude for the artful attitude ("Hermes")! ^^
