Cannot connect IOT side device to server

Hi,

I installed recently blynk server on my VPS. I can connect to the server with the app, but when i try to connect my adruino uno (via usb serial with included blynk script), it looks like the connection gets somehow interrupted.

so, this is output form script:

Connecting device at COM11 to 80.211.207.110:8440...
OpenC0C("\\.\COM11", baud=9600, data=8, parity=no, stop=1) - OK
Connect("80.XXX.XXX.110", "8440") - OK
InOut() START
DSR is OFF
Received EOF
EVENT_CLOSE
InOut() - STOP
Disconnect() - OK
Connect("80.XXX.XXX.110", "8440") - OK
InOut() START
DSR is OFF

Variables in script is:

set COMM_PORT=COM1
set COMM_BAUD=9600
set SERV_ADDR=80.211.207.110
set SERV_PORT=8440

I tried to change port in usb script, but it is only worse when i do it.
I really do not know where can be error, i hope, you do. Thanks, co-Blynkers :smiley:

Port should now be 8080 for Local Server

Oh, yes! You are right ! I do not heard about that update, what you have appended to your reply.

Thank you very much. Everything is now up and running. Thanks!

Hi Gunner and thanks for help, but apparently, i have the same problem again, but i am using correct values now… or not?

I have exact same variables in blynk USB script except port. Of course now i have:
set SERV_PORT=8080
Did anything changed again? I does not heard of, and if i did not updated the server since begin this topic. So what is going on? Maybe you could spot something what I do not.

Thanks.
//edit i did not nothing, and it somehow works. thanks anyway.
