ROS Serial Server - Unable to establish TCP Connection

[munn33b]

Hey,
I am trying to connect ESP32 to ROS using rosserial_server. When using rosserial_python instead, everything is fine, but using rosserial_server on ROS Noetic + Ubuntu 20.04, TCP Communication cannot be established

It simly stucks here while on rosserial python (rosserial_python serial_node.py tcp) everything is working.

I have built rosserial_server from source and also tried one from official repo in Ubuntu 20.04, but nothing changed
Thanking you in advance for help
