Unable to connect via 8123

I had HA up and running on a pc full HA OS. Setup DNS yesterday and all was good apps connected etc etc. Then I was setting up alexa via AWS all was good until I tried to connect the alexa app to the skill. Then I got a unable to connect message and now nothing will connect to HA. I have the terminal open and I can’t see anything wrong bots up did a core check that passed. What can I do to get back into HA? can I turn off DNS??

Thanks in advance.

You’ve left your duckdns prefix in the screenshot - might be worth editing it out :wink:

Thanks not using it now gone cloud flare. not that it completely fixed the issue. :frowning:
