Application Webservice not working since LV2021(64bit) / LV2020(64bit) was perfect

[nottilie]

Dear Community

I am facing a fundamental problem since I build my big application in LV2021.

I have included a webservice in my application and build it the last "years" with LV2020(64-bit) 

After creating the installer and installing it to a clean PC everything worked fine till LV2021(64bit). The "niembeddedws.conf" was read during launch and the application was controlable via the set TCP port 8002.

Now when the same application is build in LV2021(64bit) all seems to be fine after installation but the webservice is not running. (no listening port 8002 is there)

It is not a problem of the firewall because it is completly switched off.

After starting the Application i see in the windows event log that there is a problem (but i have no idea how to investigat or even to solve this issue)

There are three error messages all related to problems with the webservice.

Here are the entries:

appweb: Error: NI Auth Module -- Caught exception while loading NIAuth shared library

appweb: Error: Initialization for module niAuthModule failed

appweb: Error: Error with directive "LoadModule"
At line 14 in C:\Program Files\ioniTOF42\niembeddedws.conf

This is the niebeddedws.conf file (hope it is ok as text in thread, i am to sure if the attached file would have been better)

Hope anyboldy has a good idea as this topic is pending till LV2021(64bit) arrived and still here in LV2021SP1(64bit)

By the way, there are no webrelated NI services running and it is working with 2020. (no NISystemWebserver, and no NI ApplicationWebserver)

Hi Gernot,

I experiencing exactly the same issue. Did you find a workaround/solution?

Kind regards

Dear Andrea

I am sorry but I expected someone of NI is also looking onto the forum.

This seems not to be the case.

I still struggle with this problem and have had no step forward. The only thin I know if I install an older version of our software before I install the current version in parallel it works.

But this is no solution for this issue and I hope someone of NI is also reading this lines and states onto this issue.

If I have any updates I will post it here.

Dear Gernot,

thanks for your prompt answer. I have the same observations as you have about the workaround.

I have anyways opened an official support request. I will keep you posted about the outcome here.

Kind regards,

Andrea

Hi Gernot,

I managed to get this accepted as bug by NI with CAR number 2059713.

I am by now a CAR number champion: I got 4 accepted in 8 years. I don't know if I have to feel proud or just miserably unlucky 😂

Kind regards

Andrea
