office online was unable to find the specified certificate

I'm getting this error and I have the certificate with the friendly name as shown in the picture that matches the same name in the command in the powershell window. anything else I'm missing in order for it to find the certificate properly?

You can try the following methods:
1. In the domain, install the "Certificate Authority" role and complete the configuration.
2. Then, find the "Server Certificate" in IIS:
3. In the "Operation" area on the right, click "Create Domain Certificate":
Note that you need to fill in the FQDN of your oos server in the "Common Name" column.
4. Then in "Specify Online Certification Authority", select your certificate authority's certificate.
5. After completion, go back to PS and execute the command to create the oos field again.

If you want to use it on the public network, you need to use a certificate approved by the public network. The self-signed certificate cannot work properly, and you need to import the certificate in IIS before using it.
