<p>Hi,</p>
<p>Had the same issue recently on Ubuntu 18.10. OTP 19.3 wants
OpelSSL 1.0.x. <br>
</p>
<p>Make/install OpenSSL:</p>
<p>curl <a class="moz-txt-link-freetext" href="https://www.openssl.org/source/openssl-1.0.2r.tar.gz">https://www.openssl.org/source/openssl-1.0.2r.tar.gz</a> | tar
xfz - && cd openssl-1.0.2r && ./config
--prefix=/usr/local/openssl-1.0.2r -fpic && make
&& sudo make install && cd .. && rm -rf
openssl-1.0.2r creates=/usr/local/openssl-1.0.2r</p>
<p>Reconfigure/build OTP 19.3 with the flag<br>
</p>
<p>--with-ssl=/usr/local/openssl-1.0.2r</p>
<p><br>
</p>
