Hi, Thanks for your answer. I have tried the generated config from this wonderful site, but no improvement. So here is the output of the haproxy command : HA-Proxy version 2.3.20-1ppa1~focal 2022/04/29 - https://haproxy.org/ Status: End of life - please upgrade to branch 2.4.

Configure "ssl-default-bind-ciphers" as per: https://ssl-config.mozilla.org/#server=haproxy&version=2.3&config=old&openssl=1.1.1k&guideline=5.6 If you don't allow TLSv1.0 ciphers, TLSv1.0 can't be used. Also it's possible OpenSSL is so new it needs additional convincing. Share the full output of haproxy -vv, including the OpenSSL release please. > Can someone tell me what I am missing ? I have found a few messages > about adding other cipher suites, .... but nothing lead to an improvement. You will have to share more data. Full output of haproxy -vv, full ssl configuration. Can't really troubleshoot without configurations and exact software releases (openssl).
