For some reason I cannot access one of our apps via IPv4. $ curl -4v https://app.at.domain/ * Trying a.b.c.d:443... * Connected to host.at.domain (a.b.c.d) port 443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * successfully set certificate verify locations: * CAfile: /etc/ssl/cert.pem * …

Oh! I found the error, it seems the IPv4 didn’t get attached to your app properly at deploy time. It’s fixed now, will you give it another try?
