Despite several days of searching, I can't find any resources to check the MbedTLS error code "-17040". All of the error codes descriptions available are referencing only hex format errors (which the debug output does NOT give!)

The resources I was able to find did not seem to relate to my issue:

  1. https://github.com/espressif/arduino-esp32/issues/1420 does not relate due to the fact that I am not downloading or uploading files, only small amounts of data to Firebase.
  2. https://github.com/espressif/arduino-esp32/issues/1861 has the same issue (error -78) that I infrequently experienced, but I could not determine how it related to the cause of my issue.

For more details, code samples, and debug output please reference the details on the GitHub issue I posted:

Side note: I have posted a similar question on Quora recently, however, Quora no longer has a "details" area to easily add detailed information for questions asked. Therefore I wish to extend this question to StackExchange as well in order to maximize the responses I can potentially get to resolve this issue.
