Unhandled Exception when checking websites: Exception: System.Runtime.InteropServices.COMException: The object identifier does not represent a valid object.

Hello,
I'm facing an issue with the plugin. Works fine with app pools but not with app websites.
windows 2012 R2, IIS 8

Tested using an admin account / admin console.

Any clue of what could be the reason?

What if you try to do inventory instead of check? Any AppPools without name? Special characters? man. 19. jul. 2021 kl. 16:00 skrev Yannick Charton ***@***.***

That's the website part (lowercase potions) which is not working, apparently the apppool part seems fine.

Inventory try:

I've checked the site names, one includes some dots. Appart from that, no special characters.
For the apppool names, no special characters.

Can you try using the debug switch with the others? If you cant share openly, can you share directly? tor. 22. jul. 2021 kl. 10:22 skrev Yannick Charton ***@***.***

The error itself might be because a website is not assigned to a valid AppPool. Did someone recreate an AppPool without reassigning the website? tor. 22. jul. 2021 kl. 10:22 skrev Yannick Charton ***@***.***

I have an idea for a fix to this btw, it can throw an "UNKNOWN" and report back the AppPool that has the assumed configuration error.
