Recieving SSL - An invalid SSL record was received

[kahlenberg]

Hi, I changed the exp32-cam example, I can receive text messages but not photo. When I send a /photo message, in serial console I receive SSL - An invalid SSL record was received error. I think it is about the length of the messages but I could not find any hit. Can you have a look ? Thanks.

    ESP_LOGI(TAG, "Got response....%d", numNewMessages);
    handleNewMessages(numNewMessages);
