net server ip connection fail etimedout

I use nodejs net (https://nodejs.org/api/net.html) to connect pc as client to server via ethernet cable. The app connects well from one pc to server (ip 192.168.100.150:1025), but it does not connect (etimedout) to server on another pc. First, I couldn't even ping the ip address of server, but setting on pc the ipv4 to 192.168.100.151 it could ping the server, but still got etimedout. From nmap this could be relevant: 1025/tcp filtered NFS-or-IIS Warning: OSScan results may be unreliable because we could not find at least 1 opened and 1 closed port.

I don't know what I miss to get connection to server.

Edit: PC (client) has win10 OS and server is a Mitsubishi FX5 PLC. The PLC's application (GX Works3) can connect to PLC from PC. I assume that my app that wants to connect on same host and port is blocked by win10 firewall or the ESET antivirus app. I turned off firewall in ESET and temporary deactived ESET protection, but still could not connect to server.
