What is the TCP port used by the pson protocol?

Can someone tell me which TCP port the pson protocol uses for connecting IoT devices to Thinger? Our device is unable to connect when connected to a university wifi network and we suspect the router may be blocking the specific port.

Note: The network we are trying to connect to does not require a user and password, only the network password."

Hi,

it uses the TCP 25200 port and 25202 if it goes on TLS.

Hope this helps.
