Chosen solution

The www.otoc.pt server doesn't send the required "VeriSign International Server CA - Class 3" intermediate certificate.

You can inspect the certificate chain via a site like this:

You can download and install that certificate from this VeriSign web page.

Save the certificate text to a text file (e.g. VeriSign-Inc.cer) and import that file in the Certificate Manager
