Got gateway 502 error on AlmaLinux 8 server with nginx+apache. The logs were filled with lines like this:
[error] 1387293#0: *28 SSL_do_handshake() failed (SSL: error:0A00042E:SSL routine::tlsv1 alert protocol version:SSL alert number 70) while doing handshake on SSL upstream, client: 2.3.4.5, server: web. example.com, request: “GET/HTTP/2.0”, upstream: “host: “web.example.com”
possible solution
Solution for Directadmin Server
- Update file: /etc/nginx/nginx-defaults.conf
Servers without DirectAdmin may have other files that you can update.
Anyway you need to add the following lines to Nginx configuration:
proxy_ssl_protocols TLSv1.2 TLSv1.3;
proxy_ssl_ciphers DEFAULT;
And restart the webserver.
I hope it helps.
