Hello,
I have to bother you with request for some more information.
1) Please confirm the QuickOPC version you are using - is it 2021.2?
2) Please post here the piece of code that you use to switch to the SDK configuration.
3) "No SDK application configuration is available" does not look like the full error message. What is the the full message?
4) Please attach a handler to static EasyUAClient.LogEntry event at the beginning of your program, and post here all message texts that the program generates through this event when it fails under Linux.
Thank you

Hello.
This functionality (external SDK config file) is rarely used, and it has not been tested on Linux. I will test it and attempt to reproduce your issue. Please allow some time for that. I will post here when I have an update on the issue.
Note (unrelated to your problem): Some information in the SDK config file is overriden by the parameters inside QuickOPC. This include the certificate paths; setting them in the file should have no effect. The long-term goal might be to provide all values from the config file via QuickOPC API, at which point this functionality will become unnecessary.
Best regards

Thank you for the quick response!
Unfortunately this configuration does not seem to work under Linux machines, yet on Windows it does.
The error message we receive is: "OpcLabs.EasyOpc.UA.Engine.UAEngineException: No SDK application configuration is available"
We updated the paths (e.g. for the certificates) and verified that the specified folders exist on the Linux host.
Can you please provide a configuration that is compatible with Linux-based (Debian preferably) devices?
Or are there any special actions that need to be performed when reading a configuration from a Linux host?

Hello.
I am attaching the default SDK configuration, used in QuickOPC 2021, regardless of whether it is or not identical to the one you referred to.
Yes, you have to specify the entire configuration (OK, parts of it are not really used, but the principle is as such; it is not enough to specify the differences).
Best regards

That is very good news. Thanks for letting me know.
I have two more questions regarding the configuration:
Where can I find the default (XML) configuration? Is the one linked here still up-to-date?
And do I have to specify the entire configuration or is it enough to just specify the attributes that need to be updated?

Thanks for your reply.
Is there any roadmap or known date for when the operation timeout can be configured in code?

There are multiple timeout values.
If you can connect to the server, the server usually *does* respond properly (this timeout would be the OperationTimeout, which defaults to 60 seconds), by itself. Much more common are communication problems (network infrastructure) - in which case there are timeouts on connecting (e.g. EndpoitnSelectionTimeout), and mechanisms to detect disconnection (some of them are not even timeouts, but rather checking periods for keep messages etc. - it would be several pages to describe all that's involved).
Have a look at these links:

How to configure a request timeout in EasyUAClient? was created by servusintra
I would like to know whether there is any way to configure a timeout for requests in the EasyUAClient. For instance, we send a write request to the OPC UA server to write some value to some variable and now that variable does not get written due to a connection timeout (server does not respond properly). How can we make such a request time out sooner? I am unsure about the available configuration parameters and this is why I need your assistance.
We are using QuickOPC version 5.59.492.
