EUREKA!

**MUST ALTER**

```

#define Z_FRAG_MAX_SIZE 4096

#define Z_BATCH_UNICAST_SIZE 2048

#define Z_BATCH_MULTICAST_SIZE 2048

#define Z_CONFIG_SOCKET_TIMEOUT 5000

```

*MOST IMPORTANT* seems to be the line `Z_CONFIG_SOCKET_TIMEOUT 100`from 100 to 5000. Feel free to experiment with lower values (it seems to work with 1000).
