I am using Lwip-2.0.3 and running a basic HTTPS MbedTLS application to
request MyIP. When I connect the application to a server running on my PC,
it works fine, but when I try to connect to a remote server "api.ipify.org"
I quickly run out of heap bcz LWIP is consumes much memory. Sometimes, I the
application just blocks.

Problem only with this host?

I tested a libcurl with MbedTls (on Win-10) and there is an issue
with the certificate of api.ipify.org.
With '-v --tlsv1.0 https://api.ipify.org':
  curl: (51) Cert verify failed: BADCERT_NOT_TRUSTED

Maybe related?
