Fwd: Nginx Server : fatal Error from Server

Vadivel P

Nginx Team,


Creating Nginx server in local setup.


Versions we use  :

nginx version: nginx/1.18.0 (Ubuntu)


OpenSSL 1.1.1f  31 Mar 2020


OS Version

No LSB modules are available.

Distributor ID:    Ubuntu

Description:        Ubuntu 20.04.1 LTS

Release:               20.04

Codename:        focal


From  Nginx server error log :

2021/03/05 13:56:19 [crit] 82641#82641: *5 SSL_do_handshake() failed (SSL: error:14201044:SSL routines:tls_choose_sigalg:internal error) while SSL handshaking, client:, server:


We are able to see client hello packet from client & server send [Alert] internal error as response to client instead of server hello. SSL handshake is failing here.


Please let me know any changes needed in nginx cipher config. Coz, from client side DUT is trying to initiate connection to server and server declining it.
