Server not work with a real charge point about java-oca-ocpp HOT 7 CLOSED

You need to implement your own logic where the template code you copied from the wiki says " // ... handle event" and "return null".

hi @bantu, thanks for the answer.

I am doubting if that is really the problem, since the handle event logic that you mention, I understand that it is at the OCPP (application protocol) level, however, looking at the network traffic with wireshark, the handshake at the TCP (transport layer) is not carried out. In this way, the connection to the websocket cannot be made.

I have done more tests. Start a client on another machine with the same library and the result is the same. The client generates TCP requests to establish a connection with the server, but the server does not respond to the TCP requests (the TCP handshake does not take place):

On the other hand, when the client and server are on the same machine, the connection is made without problems...

@bdevia Sounds like you have network problems in general.

@bantu the truth is that I don't think it's a network problem, since with the library https://github.com/mobilityhouse/ocpp, the connection works perfectly:

Have you performed tests between client and server on different machines? I'm thinking that it may be a problem with my own equipment (architecture for example) that causes the library to not work at the network level.

it looks like your two tests are on two different ip networks (172.15.200.0/24 vs. 192.168.41.0/24)

Have you performed tests between client and server on different machines?

yes, in the past

Yes, I have two different networks:
172.15.200.0/24 internal test network.
192.168.41.0/24 production network.

I have been carrying out tests on both networks, making sure that both client and server are on the same network to rule out firewall problems.
I have changed the server to the computer with IP 172.15.200.104 (to rule out that the problem is with my machine), while the client (simulated with the library) is 172.15.200.101, however the connection does not work either:

It is possible that the library is currently failing, so it would be helpful if someone can replicate the examples from the wiki, to see if the problem is with the library.

I have already found the problem, when it set the host as "localhost", the server does not enable the service for the IP of the private network as in other services. In this way, it is advisable to change the host directly to the IP instead of "localhost".
