Customer receiving Umbrella error message when trying to access our Community portal

Customer has reported the following error when trying to access our Customer Support portal built on Community.
When I try to logon to support page I get an Umbrella error and can not access this support page (this is done from an different client without Umbrella). We have contact Cisco Umbrella for a solution, this is there reply:
This browser warning from Umbrella is caused by the certificate on the site not being chained correctly. CAs like Godaddy typically sign certificates with intermediate CAs. These intermediates need to be chained in the certificate chain on the web server so the browser can validate the whole chain. Some browsers will automatically do this chaining as a way to fix this server-side certificate misconfiguration and prevent errors in the browser. However, strict checking (which we do) of the chain will fail.

You can do a test with third party sites like this which show this chaining error:

Other testing sites:

Explanation from Godaddy on Intermediate certificates:

To summarize, the solution is to fix the certificate used on the web server so it chains correctly."

Our support team asked the customer to try different browsers and they confirmed the same problem with IE 11 and Edge.

Does anyone have any suggestions as to how we can help our customer resolve this access issue?
