wrong certificate : Common Name (CN) myrouter.io, Organization (O) Comcast Corporation Common Name (CN) COMODO RSA Organization Validation

Dear,

Please help on my 5 comcast Static ips are connected: Internet --> Comcast Modem/router --> additional Opnsense Router --> Web Server.

1.Comcast router has its own certifcate: Common Name (CN) myrouter.io, Organization (O) Comcast Corporation

2.Opnsense has also Letsencrypt certificate for Web Server app.

3. when web-browser from an internal computer behind Opnesen router tries to access the web server app like gitlab.xxx.com, it says the errror :"NET::ERR_CERT_COMMON_NAME_INVALID"

and it points Comcast router certificate in Comcast router instead of Opnsense letsencrypt certificate.

4. It seems Comcast router certificate is for web GUI 10.1.10.1 of Comcast router. How can I sove this problem? Thanks
