The website is loading fine but I can see a lot of exception messages on the log files.
Those are all realted to
certificates as you can see on the below example:
Exception: System.InvalidOperationException Message: The certificate was not found. Store: My, Location: LocalMachine, FindType: FindByThumbprint, FindValue: B6D2B200ABD73D686DA3F7AB0B8CE34E10657886, InvalidAllowed: False.

Please note that I've installed another Sitecore instance (a 9.0.1 this time) on this same machine and that I had a few certificate issues during the process.
The first instance installed was working 100% before installing the second one. After the second one, the first one is getting the above-mentioned error messages.
So I'm pretty sure the current issue is somehow related to this, but I can't find the exact cause.
When I open my Windows Certificate Manager I can confirm that all certs for this given instance are still there:
And even the
Certificate Issuer is there and still valid as well:
Any insight would be hugely appreciated.
