Comodo SSl on IIS

I have two domains on the same server, each with a Comodo SSL certificate. Unfortunately, one of the certificates is not functioning correctly, and its subdomains are directing to the incorrect SSL. I am using Windows Server 2019 with IIS 10, and the SSL is issued from Comodo SSL (wildcard). If you've read the above, type "I can do it." Please do not apply unless you are an expert in IIS with Comodo SSL. This task needs to be completed today as soon as possible and remotely.
