Note that this is an ESP32 forum; you may be better off asking a forum that is more ESP8266-oriented.

Maybe https://github.com/espressif/ESP8266_NONOS_SDK/issues is a better place for this question.
And for the SSL connection, maybe you can try the command AT+CIPSSLSIZE to enlarge the SSL buffer size firstly.
