SSL/TLS handshake failure: protocol error

[golfvert]

Hello,
While trying to use aria2-pro docker image, I have this SSL/TLS handshake error when accessing https://opendata.dwd.de
I have tried to disable check certificate, no change.
It looks like the site I am reaching may use SSL/TLS parameters not supported by aria2-pro.
When looking at https://www.ssllabs.com/ssltest/analyze.html?d=opendata.dwd.de&s=141.38.2.22
the web site receives an A+ and all seems fine.
Any idea what might be causing the issue ?
What are the known working SSL/TLS parameters for aria2-pro ?
Thanks.

Looking at aria2/aria2#1494 shows that this is apparently an issue with openssl and some websites... Using gnutls seems to fix the issue.
