Troubleshoot ESP32 Remote Update, Encryption Issues -- 2

I'm currently having issues with the OTA feature on my ESP32 Development Board. Particularly, I'm unable to update firmware remotely, the OTA process is not reliable and the encrypted firmware updates are failing.

- **ESP32 Background Information:**

I'm using an ESP32 Development board for this project. The application running on this hardware was developed using Arduino.

- **Necessary Skills Most Needed:**

A freelancer with advanced knowledge of ESP32 and an understanding of the OTA process including familiarity with encrypted firmware updates will be best suited to tackle this issue. Proficiency in Arduino is also necessary. Given that this project deals with the inability to update firmware remotely, familiarity with networking would be an added advantage.

In a nutshell, the key task here will be to ensure the firmware can be updated via OTA reliably, without any impedance from encryption.
