Server is unavailable

[tom040264]

Hi,

I tried to solve the problem by using of this tread but without any successes. For 20 minutes everything worked perfect and I did some changes in the ComServer (I tried to add a command). Then I tried to load the SCADA-Page as usual, but I got the message “Server is unavailable.”

This is the WebSettings file:

The CPU load of ScadaServerSvc.exe is 0.
Any idea?

See the log of the Server

See the file C:\SCADA\ScadaServer\Log\CalcEngine.cs with the source code

Open CalcEngine.cs and go to Line 523, column 56
Probably you inccorctly use GetBit function.
All the formulas from Administrator are included in CalcEngine.cs. You should fix the formula in Administrator.

[Mikhail]

Server cannot start correctly, that’s why the web app doesn’t connect to it.

[tom040264]

I fixed the formula, and it works now. Thank you!

The Agent service doesn’t work. If you need more info, create a new topic.

Hi,
The above link is not public.

[KeanoC]

Im experiencing a similar issue where when I try logging in to the websation it says server unavailable and the instance manager is showing that the status is not supported but I receantly migrated from 5.4.1 to v6

[Mikhail]

The web app does not show its status, therefore it’s written that it is not supported. To fix the issue, check log files of the applications.

[KeanoC]

Error connecting to SCADA-Server: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

This is the error I find in the logs how do I fix this?

[Mikhail]

Restart SCADA-Server, then check ScadaServer.log. Copy start messages from the log here.
