Error is seen only when using the domain name and not the IP address. Make sure the domain name resolves to the WAN IP of SonicWall.

For eg, a Certificate is issued for the domain SonicWallssl.com. The domain sonicwallssl.com should resolve to the WAN IP address of the SonicWall. This can be done by the CA or a DNS authority.

Ensure that the certificate is issued for the correct domain/common name. Click on the Not Secure message as shown below.
Click on the "your connection is not secure" message and then the certificate icon.
On the certificate that opens up, verify that the domain mentioned ("Issued to" field) is the same or the sub-domain of the URL you are using to access the HTTPS management page.
NOTE: If using a sub-domain, make sure the certificate is issued for the wildcard for your domain.
If the issued domain is different from the FQDN used to access the management page, please contact the CA and get the same changed on the certificate. The certificate may have to be rekeyed by creating a new CSR or a new certificate may have to be issued.
