SecureWrite example causing bootloop

[arshaver]

I'm running InfluxDB-Client-for-Arduino version 3.1.2 on an Adafruit Feather HUZZAH ESP8266. When trying to run the SecureWrite example without any modifications but adding my InfluxDB cloud and WiFi credentials, I'm getting a boot loop.

Here's what I'm seeing on the serial monitor:

Any suggestions as to what might be happening?

@arshaver, thanks for reporting this. Unfortunately, I can confirm it is a bug.

As a quick workaround, replace in the library sources in src/InfluxDBClient.cpp line 230 with: _httpClient.setUserAgent(FPSTR(UserAgent));
