      Hi All,

      I just change to kopano community edition and i think it is great! However i got a problem if i want to access the webapp application behind my apache proxy.

      I get my logon screen, but after i login i get an error: 404 it cant find /webapp/webapp

      How can i resolve this? My proxy settings are:

      <VirtualHost *:443>
      DocumentRoot /var/www/
      ServerName mydomain
      ServerAdmin ben@example.com
      # Indexes + Directory RoNoneot.
      DirectoryIndex index.html index.php
      ProxyPreserveHost On
      SSLProxyENgine On
      SSLProxyCheckPeerCN off
      SSLProxyVerify none
      SSLProxyCheckPeerName off
      ProxyVia full
      <proxy>
      Order deny,allow
      Allow from all
      </proxy>
      ProxyPass / https://192.168.2.8/webapp/ flushpackets=On keepalive=Off
      ProxyPassReverse / https://192.168.2.8/webapp/
      SetEnv proxy-sendchunks 1

        Hi,
        in /etc/kopano/webapp/config.php
        find this line: define(‘INSECURE_COOKIES’,false); and set it to true: define(‘INSECURE_COOKIES’,true);
        restart apache2 and test if it works.

          Hi this is not the sollution. I believe it had something to do with the url. HTTPd want to redirect me to https://xxxxxx/webapp/webapp/

          And ofcourse it Can not find the path?

            Hi,

            the location in your ProxyPass is wrong, replace / with /webapp should work.

            ProxyPass /webapp https://192.168.2.8/webapp/ flushpackets=On keepalive=Off
            ProxyPassReverse /webapp https://192.168.2.8/webapp/

            We do not use flushpackets=On keepalive=Off.

                Hello @ckruijntjens,

                i bet your apache config on your real webapp-server is rewriting from https://192.168.2.8 to https://192.168.2.8/webapp

                if it does and your proxy does the same and it will append to https://192.168.2.8/webapp/webapp
                change your config in proxy so it wont rewrite and access the server without /webapp. the rest will be done on the webapp-system.

                    @coffee_is_life hi,

                    i just went to my config again. If i enter the url manual it all works. However when i enter webmail.xxxxxxxxx.nl it redirects me to the root of nginx. I want to redirect to webmail.xxxxxxxx.nl/webapp

                    How can i do this in nginx without the error to many redirects?

                      Hello @ckruijntjens,

                      im not familiar with ngnix configuration, so im not much help there, After googling “ngnix config rewrite rule” i found this:
                      https://www.nginx.com/blog/creating-nginx-rewrite-rules/

                      so i thing there must be something like this:

                      server {
                      rewrite ^(/webmail.xxxxxx.nl/)$ $1/webapp break;
                      rewrite ^(/webmail.xxxxxx.nl\//)$ https://webmail.xxxxxxxx.nl/webapp break;
                      }
                      

                      the breake will cause nginx to stop the rewriting otherwise it may append these changes.
                      The “$” in the regex is used to define that here is the end of the url.

                      you need to check if ngnix is interpreting http and https before the regex, then you need to change
                      rewrite ^(/webmail.xxxxxx.nl//)$ https://webmail.xxxxxxxx.nl/webapp break; to this:
                      rewrite ^(https://webmail.xxxxxx.nl//)$ https://webmail.xxxxxxxx.nl/webapp break;

                      in addition nginx provides a rewrite_log:

                      Syntax: 	rewrite_log on | off;
                      Default: rewrite_log off;
                      
                      if set to on, nginx will log rewritings into error.log on level NOTICE
                      

                      try with these and report back :)

                        Hi @Coffee_is_life

                        ProxyPass /webapp https://192.168.2.8/webapp/
                        ProxyPassReverse /webapp https://192.168.2.8/webapp/

                        I Just did the above in my apache (httpd) server to check if this is correct. However if i do the above it get an access denied error. (No access)


                        Forbidden
                        You don’t have permission to access / on this server.
