Hi @sam1, @jcoleman, @weertske,

when you generate your certificate, add your _IP-Adress_ and _DNS_ under _Subject Alternative Names_. As explained under point 6. in **[How to Install a Self-Signed Certificate](https://www.docs.inductiveautomation.com/docs/8.1/platform/gateway/config/web-server-settings/secure-communication-ssl-tls#how-to-install-a-self-signed-certificate)**.

Cheers
