Getting error {esp-tls: mbedtls_ssl_handshake returned -0x10} when router gets off

Im using esp-mdf 3.3, was testing with a scenario that what is router turn off and after a time it power up again..

So while ESP running I turned off the wifi and ESP crashed. Here are the logs:

So I read an issue here and put a delay in static mdf_err_t event_loop_cb inside mesh_exp.c

`case MDF_EVENT_MWIFI_PARENT_DISCONNECTED: MDF_LOGI("Parent is disconnected on station interface");

        vTaskDelay(pdMS_TO_TICKS(3000)) //added for TLS issue

        if (esp_mesh_is_root()) {
            mesh_mqtt_stop();
        }
        break;

Now it is not crashing but throwing this error:

heap_size: 10912, min_free_heap : 540 D (379304) Brain: Dispatching Energy State as Mesh Frame I (379304) Brain: Encoded Message, bytes written: 70, encode_status: 1 E (379436) **esp-tls: mbedtls_ssl_handshake returned -0x10** I (379436) esp-tls: Certificate verified.

Now when I power up the router this shows up.. Although I have alot of heap available. I also checkout mbedtls/port/net_socket.c to master (updated). Still having this issue.
