      I’m messing around with a weird problem in Kopano Webapp. I’m using kopano within docker containers from following project

      https://github.com/zokradonh/kopano-docker

      and the latest version of Core and Webapp (I tried with the last 5 Versions)
      Webapp : 3.5.7.2298+1289.1
      Core: 8.7.81.48.39640ec78-0+233.1

      The problem is, that everything is running perfect besides the one issue that i cannot answer or forward to an email.
      If I create and send a new email everything works as expected. When I answer to an email the browser and the proxy report a 502 bad gateway issue.

      I tried to connect to the webapp with and without a proxy. So the direct connection over port 9080 results in the same issue. So I can exclude a proxy issue. I tried different versions and I tried to log things but the only log I could get related to this problem is the log from the proxy server.

      kweb log

      X.X.X.X - - [27/May/2019:07:05:44 +0000] "POST /webapp/kopano.php?subsystem=webapp_1558940724801 HTTP/1.1" 502 40

      If I manually connect to this site I get follow information within my browser

      Thanks

      I’d really appreciate your help. This is the last part to complete my project.

          Yeah I saw that article too. Ok in that case I will test the whole project with my official supported Kopano packages and will write my experiences to this site. Thanks for the quick reply.

            Ok I tried the whole setup with my official supported packages.

            Version

            kopano-server 8.7.1.0-0+1.1
            kopano-webapp 3.5.6.2298+94.1

            The problem still exists. After answering the mail, it looks like that the webapp tries to POST but gets a 502 response. After that it tests if the kopano server is online. Because this response is good it tries it again. This process loops until i reload the site or I sign out from webapp. After a few minutes the browser gets really slow. I don’t know

            XHR POSThttps://XX.domain.local/webapp/kopano.php?subsystem=webapp_1558948911629
[HTTP/1.1 502 Bad Gateway 65ms]

XHR GEThttps://XX.domain.local/webapp/kopano.php?ping
[HTTP/1.1 200 OK 32ms]

XHR POSThttps://XX.domain.local/webapp/kopano.php?subsystem=webapp_1558948911629
[HTTP/1.1 502 Bad Gateway 63ms]

XHR GEThttps://XX.domain.local/webapp/kopano.php?ping
[HTTP/1.1 200 OK 31ms]

XHR POSThttps://XX.domain.local/webapp/kopano.php?subsystem=webapp_1558948911629
[HTTP/1.1 200 OK 109ms]

XHR POSThttps://XX.domain.local/webapp/kopano.php?subsystem=webapp_1558948911629
[HTTP/1.1 502 Bad Gateway 71ms]

            Maybe this is related to my docker setup? I changed the docker-compose.yml https://github.com/zokradonh/kopano-docker a bit. But I don’t think so because any other Request, if click through the webapp or send a new mail, does work

              The problem still exists.

              can you execute the following command to make sure that you are actually using the version you think you are using?

              docker-compose exec kopano_webapp dpkg -l | grep php7-mapi

              Yes, this is because php-mapi is segfaulting. This causes a “bad gateway” for the webserver when it happens.

              EDIT: when rebuilding the containers with the core:final repo you will not be able to start webapp because of a too old kwebd in that repo. the container will fail with kopano_webapp | 2019/05/27 12:04:25 /etc/kweb.cfg:4 - Error during parsing: Unknown directive 'alias'.

              I have triggered newer builds for kweb in pre-final and final so with the next Kopano update a newer kweb will be available there. Current plan is to push 8.7.3 to core:pre-final next week, then a week later to core:final.

              EDIT2: when you go back to https://github.com/zokradonh/kopano-docker/commit/c5756e30c9170744abcd39aacd2c1121af6d893f#diff-b6920d9083c8e76685bcc8db34b8c9bb then you should be able to rebuild the webapp image (as it back then still used apache+mod_php and not kweb+php-fpm.

                docker-compose exec kopano_webapp dpkg -l | grep php7-mapi
ii  php7-mapi      8.7.81.48.39 amd64        PHP bindings for MAPI

                Oh your intention was right, after building and tagging the supported images again

                make build-all
make tag-core
make tag-web
make tag-webapp

                and using this tags in .env the output is

                php7-mapi                                 8.7.1.0-0+1.1                      amd64        PHP binding

                and everything works.

                Big thanks

                The most important part for me was that the supported packages will work. Now that they work again I will wait for the next Kopano update to test the opensource packages.

                I love Kopano and together with docker it’s really flexible. Thanks for this project and the awesome work.

                  Just to have it said: there is nothing as a “community edition” or “open source edition” what you refer to are simply nightly builds of our development branch. these have to pass a set of automated tests to be pushed to our download server. If you want to use this in a serious deployment the recommendation is to get a subscription (which will then also open up our support to you and your customer) and use our supported packages.
