Cannot access to HA via internal IP, SSL issue

Third party integrations
1

Hello,

I’ve configured HA to work with Letsencrypt:

  1. Added an entry for my subdomain to Cloudflare to point to my static IP.
  2. Installed Letsencrypt and received ssl for this domain.
  3. Added my external subdomain to the network section in HA settings.
    Now I can connect via external URL directly and/or via APP but, could not connect via internal URL or LAN IP due to ssl name mismatched error.
    I’d like to access to HA locally when I at home and connect via external when I’m away.
    Could you share your ideas and solutions please?
    Btw: using 8123 port and created port forwarding for this port number and local IP to accept incoming connection.
    Best regards.

You should use ‘split brain DNS’ to allow the subdomain to resolve to your local ip. Then just use the subdomain name for both internal and external access.
