You might have just observed an unhandled exception that breaks HTTP API settings unexpectedly. You can achieve what you wanted by writing some simple PowerShell scripts, so that IIS Manager won't be there in your way.
Has anyone else seen this IIS Binding bug?

Recently while using both IIS 8.0 and IIS 10.0 we have found a peculiar bug.
When removing a site from the IIS we stopped the Site from the IIS window then removed the directory. Returning to the IIS window we clicked "Content View" under the same stopped site. IIS threw an error.
After the error the certificate binding for that site (and consequently any site on the same port) was removed, temporarily causing a service outage.
After simply re-binding the certificate to the site on port 443 service was restored, but now you know.
Anyone else see this?

What error did IIS throw? Please post detailed error information. -

2023-10-02T14:00:10.3966667+00:00 The error IIS throws is generic. As follows. I posted this just to raise awareness of the bug and to check if we were the only ones who had seen it.
Following this, opening the binding screen will crash IIS.
The crash in event viewer begins thus:
And proceeds to this before the generic Application error above it, not pictured.

2023-10-02T14:05:07.9366667+00:00 Please note that when IIS crashed due to checking the binding it seems to reinstate the binding. This was not our use case the first time, so the certificate was never rebound in our Production environment.
This creation process never occurred in our Production environment, only while testing and immediately crashing IIS by opening the Bindings screen. The initial error (Could not find part of the path) does not crash IIS.

2023-10-03T13:41:36.9233333+00:00 It is. I posted this to raise awareness and inquire about this error. We were able to restore functionality within an hour due to good internal communication surrounding the event.
