TLS connection was non-properly terminated

[ErwanGalline]

Hi ,

I try to access wallet API using CURL command (ignoring certificate) :
curl -k https://localhost:8090/api/settings/sync/progress

Running the command inside the container works properly but when i try from host machine i got :

*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8090 (#0)
* found 148 certificates in /etc/ssl/certs/ca-certificates.crt
* found 597 certificates in /etc/ssl/certs
* ALPN, offering http/1.1
* gnutls_handshake() failed: The TLS connection was non-properly terminated.
* Closing connection 0
curl: (35) gnutls_handshake() failed: The TLS connection was non-properly terminated.

I don't understand why '-k' does not allow me to ignore certificate and access https server from outside ...
Thanks for your help
