#85407 Hi dear experts,

I set up a secure webserver on Arduino ESP8266 using BearSSL with a server certificate and private key. For MQTT I'm using PubSubClient library and secure connection with client AND server certificates.

The webserver works fine as long as the MQTT connection has not been established. After connecting to the secure MQTT broker (mosquitto running on a Raspberry) the webserver on the ESP8266 is not responding any longer. The MQTT connection, however, works fine.

Does anyone know, if it is possible with BearSSL to have 2 secured connections opened on the ESP8266 at the same time or is the number of secured connections limited to 1?

Best regards,
Ladi
