We have a server running APACHE 2.4 and a SSL vhost with SSL and a LE cert created using the certbot. Everything is working fine until we ENABLE h2 on the server. Then, Chrome and Firefox continue to work but Safari and IPHONE (using both Safari and Chrome) started to see a SERVER UNEXPECTLY DROPPED THE CONNECTION error.
We have the same configuration on another virtual with a Comodo certificate so we think is something related to the LE config.
We remove a lot of ciphers from the default config and we put this but still not working:
SSLProtocol TLSv1 TLSv1.1 TLSv1.2
Any ideas where to look? Thank you!
