Connection issue on io.adafruit with MQTT and SSL Moderators: adafruit_support_bill, adafruit

[pandiculation]

Hello!

It seems like the MQTT connection with SSL can't be established for the past 3 weeks.

In more details, I'm using the "mqtt_esp8266" example provided in the Arduino software and when I use it as such (and update the wifi and Adafruit.io information) it works like a charm. When I try to use an SSL connection by changing:

Code: Select all | TOGGLE FULL SIZE

#define AIO_SERVERPORT  1883
WiFiClient client;


to

Code: Select all | TOGGLE FULL SIZE

#define AIO_SERVERPORT  8883
WiFiClientSecure client;

The MQTT connection fails to go through whereas it used to work very well. Has any update being performed on the io.adafruit servers?

Please let me know if there is anyhting I can do to help debug the situation.

Thanks!

Has somebody encountered the same problem?
Is there any other parameter to change?

This situation really puzzles me as my code used to work.

Thank you in advance for any help.

Hi pandiculation,

Are you using the following configuration with the Arduino IDE?

* ESP8266 Board Support Package 2.5.1
* Adafruit IO Arduino Library v3.2
* Adafruit MQTT Library v1.0 (or above)

Hi brubell,

Thank you for helping.

I use:

Adafruit MQTT Library 1.0.3
Adafruit IO Arduino 3.2.2

Regarding the board, I use:

esp8266 by ESP8266 Community version 2.5.2

so I think I'm aligned with the versions you mentionned.

FYI, I use a Wemos D1 mini Lite board
