Certificate for this server is invalid

Hi there,

I think my DuckDNS / Lets Encrypt addon has failed to renew the SSL and now I can’t get into home assistant. I am unsure how I can access the control panel in order to fix the issue when local / duckdns URL both fail to let me in.

What are my options? There must be a way in which I can get in to trigger the SSL to renew or disable SSL all together in order to gain access. Would disabling my port forwarding for the DuckDNS enable the local IP to work and let me in that route?
