ScadaComm error

[Artos9]

Hello,
After porting ready project from Windows to Linux server, I can’t start ScadaComm. I have an error in ScadaCommSvc.log

Thank you.

Hi,

Likely SCADA-Server can’t start. You should check its log. Make sure that you changed server directories in the project before uploading (Server – Common Parameters).

Yes, I change it.

Hi,
I see that ScadaWeb and ScadaServer are working still on ‘localhost’, is it correct? In case of Scada installation of my Linux server?

I see that ScadaWeb and ScadaServer are working still on ‘localhost’, is it correct?

“localhost” means the current server. If all the apps are installed on the same server, it’s OK.

[Artos9]

I’m not sure, that I understand the idea.

Scada is installed on Remote Linux server (http://mywebserverexample.com/scada), as WebServer is Apache.
But additionaly Scada is configureted in cooperation with localhost.

I’m sorry for misunderstanding Web&Server administrations is new for me.

Hello Mr. Mikhail,

I had a scada communicator error problem, then I tried to run the “Hello world” project but it also didn’t work.

https://drive.google.com/file/d/1H6bTrWVkFmA3d-uNh4iDgRU0sGN7KtOl/view?usp=drive_link
help me please.
thank you

Hello,
The log file says Communicator cannot connect to the SCADA-Server service.
Also check ScadaServer.log
In general, I suggest to use Rapid SCADA 6 instead of 5.
