I am trying to install ssl certificate on my ubuntu server 20.04

I have downloaded ssl files and put them in /home/ubuntu (will change once it works):

  • api_limitlesssoft_com_key.txt
  • api.limitlesssoft.com.p7b
  • api.limitlesssoft.com.crt
  • api.limitlesssoft.com.ca-bundle

Now what I have done is edit Virtual host file to look like this:

LoadModule ssl_module modules/mod_ssl.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

<VirtualHost *:80>
        ServerName api.limitlesssoft.com
        ServerAdmin [email protected]

        ProxyPreserveHost On
        ProxyPass / http://127.0.0.1:5000/
        ProxyPassReverse / http://127.0.0.1:5000/

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

<VirtualHost *:443>
        ServerName api.limitlesssoft.com
        ServerAdmin [email protected]

        ProxyPreserveHost On
        ProxyPass / http://127.0.0.1:5000/
        ProxyPassReverse / http://127.0.0.1:5000/

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SSLEngine on
        SSLCertificateFile /home/ubuntu/api.limitlesssoft.com.crt
        SSLCertificateKeyFile /home/ubuntu/api_limitlesssoft_com_key.txt
        SSLCertificateChainFile /home/ubuntu/api.limitlesssoft.com.ca-bundle
</VirtualHost>

and for some reason only http one does work.

a2enmod ssl returns that it is already running I have ran sudo ufw 443 and it is enabled

And here is my application startup (when debugging it works on https)

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace api.limitlesssoft.com

    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.Configure<ForwardedHeadersOptions>(options =>
            {
                options.ForwardedHeaders =
                    ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseForwardedHeaders();

            app.UseHttpsRedirection();

            app.UseStaticFiles();

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }
}

    api.limitlesssoft.com just times out on port 443. It works on port 80 though. Did you check your firewall? Jul 19, 2021 at 22:15
  • @MichaelHampton What do you mean by that? Jul 19, 2021 at 22:22
  • I added netstat -a -n results and as i can see there is port 443 Jul 19, 2021 at 22:23
  • Btw ufw is disabled Jul 19, 2021 at 22:25
  • I also enabled ufw and still not working (see output in edited question) Jul 19, 2021 at 22:30

Found solution in Connection refused HTTPS on Apache and it is marked as -1 points.... problem was in routing... port forwarding didn't forward port 443, only 80. That is why it was not working.
