xrce nano-client via serial - only 4 messages published?

I'm using the xrce nano client with Arduino via serial (USB serial to be exact) on an Arduino Due. I set LWIP and IPv4 options to disabled because the board does not have wifi. I am trying to use a slightly modified version of the sensor-writer-serial example below. It appears that the writer sends out only 4 messages every time I reset the board. (I only see the TX light flicker 4 times and see 4 messages in RTI Admin console, but the onboard LED that I'm using for a heartbeat keeps on going). Note that this only worked after I switched to a best effort stream_id.

DDS-XRCE Exception (28)

Hello, I'm a student at Hungary, and i got a project to do at the university, which is include DDS-XRCE.
I have to read sensor data from a temperature sensor with an "NodeMCU Lua Amica Module V2 ESP8266 ESP-12F WIFI Wifi Development Board with CP2102". I'm trying to use the SensorWriterUdp arduino program from the RTI GitHub, but it only trows "Exception (28)" as soon as it connects to the nano-agent.
I cound't find any information what it could be. If anyone knows please help me out!

Thank you so much!
