Problems with messages OSC server 2.3.1, client 2.0.8

Hello! I have problems with OSC on server 2.3.1. I am not receiving the duration status of the playing videos. Can somebody help me? On the server I have the default port configured (6250), the same on the client for reception. I come from migrating from server 2.0.7, where it worked fine. I saw in the forum the same problem on the 2.2 server, but I did not understand the solution.

Thank you!

is there some reason you are using old version of client? It should work with current versions of both server and client.
