HA Yellow. after adding duckdns and let’s encrypt i rebooted Yellow but can no longer connect either locally or externally

Configuration
1

Installed duckdns and let’s encrypt. I thought it was working, accessed through duckdns address but iOS app could not connect. Decided to reboot Yellow after reading community posts.
No I can no longer acces Yellow at all. Is there a way around or do I need to factory reset the Yellow?

Letsencrypt is included in DuckDNS. You do not need to install it. Just agree to the terms in the DuckDNS config.

You should be accessing https now, not http. You may need to update your bookmarks.

That was not the issue, i had no access whatsoever anymore. But never mind, did a factory reset
