ok, forcing NIO implementation makes tomcat service to listen port 8443 but now I do a test using curl and the client does not get response from the server.
$ curl -I 'https://XXXXXXXXXXXXX:8443/authentication' -H 'Authorization: Basic XXXXXXXXXXXXX' -H 'Content-Type: application/json' -H 'Accept: */*' -v * Trying XXX.XXX.XXX.XXX... * TCP_NODELAY set * Connected to dev.retex.global (XXX.XXX.XXX.XXX) port 8443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH * successfully set certificate verify locations: * CAfile: /etc/ssl/cert.pem CApath: none * TLSv1.2 (OUT), TLS handshake, Client hello (1): any thoughts? ________________________________ From: masber masber <mas...@hotmail.com> Sent: Saturday, 1 December 2018 14:45 To: users@tomcat.apache.org Subject: not able to setup tomcat 7 to use port 8443 Dear tomcat community, I am trying to setup tomcat 7.0.69.0 on port 8443 but for some reason no service is listening that port after tomcat is rebooted. I uncommented the following part in server.xml <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" /> And then just rebooted tomcat but sudo ss -nolpt | grep 8443 shows nothing what am I doing wrong?
