openssl_server example, Safari/macosx: SSL_accept() fails with 0

[hpanther]

I have built the openssl_server example, using the default SSL cert and key. When I connect to the ESP32 via curl, this works:

Code: Select all

However, when I attempt to load the page with Safari on macosx 10.13.16, I don't get the page. Safari asks to confirm the insecure page, but then doesn't load it, instead asks for the confirmation again. In the log, I added the output of result values. You can see that the failure occurs twice as Safari loads the page again immediately.

Any help with this issue would be appreciated. Thanks!
