[LaudixGit]

Describe the bug
Error during createSelfSignedCert
".Guru Meditation Error..."

How To Reproduce
Steps to reproduce the behavior:

1. run the Self-Signed-Certificate - no error
2. run the REST-API example - Meditation error

Expected Behavior
Create self-signed certificate without errors

ESP32 Module

Software (please complete the following information if applicable)

• IDE and Version: Arduino 1.8.15
• OS: Ubuntu 18.04.6 LTS

I noticed 2 requirements I did not expect:

• wifi must be included (#include <WiFi.h>) even though my device uses ETH the certificate creation fails without wifi.
• Cannot open a SPIFFS file prior to createSelfSignedCert in the same function. Using a helper function stopped the Meditation error. (even closing the file didn't help)

Tweaking your examples just slightly worked for me

Observe the addition of the "certFileExists" function instead of using SPIFFS.open in the same function prior to createSelfSignedCert.

Closing this because I am only sharing what worked for me - maybe it'll give others insight - but don't have an issue to solve.
