      My server Fog (CentOS 😎 is in Https. On the client (CentOS 7) when I start the Fog service, I get in its log:

      --------------------------------Authentication--------------------------------
------------------------------------------------------------------------------
 1/27/2020 11:16 AM Client-Info Version: 0.11.17

 1/27/2020 11:18 AM Middleware::Communication ERROR: Could not download file
 1/27/2020 11:18 AM Middleware::Communication ERROR: Error: TrustFailure (Authentication failed, see inner exception.)

      In the log of the server /var/log/httpd/access_log, nothing is reported for that client.

      So the client receives no information about the tasks on the server.

      Another thing is the status of the Fog service on the client: this status claims that the file /opt/fog-service/service.lock does not exist. But it exists and contains the Pid of the process.

      systemctl status FOGService -l
● FOGService.service - FOGService

      Thanks for your help.

        Not exactly sure why this happens. Do you use a custom HTTPS certificate?

        As well you might try the latest release that came out yesterday: https://github.com/FOGProject/fog-client/releases/0.11.18/

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          We do not use a custom certificate.
          I have installed this new version on the client. The error message in fog.log is now :

          --------------------------------Authentication--------------------------------

          On the server, I have had a log (in /var/log/httpd/access_log) when I installed the client :

          148.60.3.96 - - [27/Jan/2020:14:16:38 +0100] "GET /fog/management/other/ca.cert.der HTTP/1.1" 200 1287 "-" "-"

          But, after, when I restart the Fog service on the client, nothing is logged on the server.

            Well that is interesting. I am fairly sure we have seen this happen a few days ago already but I can’t seem to find the topic. Possibly this was lost when the forum went down. Right. This is probably the case.

            So let’s try to get the information back together. Please run wget --no-check-certificate https://fogus/fog/management/other/ssl/srvpublic.crt on your CentOS client and post output here.

            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                @adrien17 Have you modified the apache config by an chance?

                  The apache configuration of our fog server is generated by fog

                  Fog Version: Fog 1.5.10
                  Server OS: AlmaLinux release 8.8

                    @adrien17 Ahhhhh, should have remembered this earlier. Unfortunately there was an issue in the config being generated. Please edit /etc/httpd/conf.d/fog.conf and search for the line

                    SSLCertificateChainFile $webdirdest/management/other/ca.cert.der

                    and change to

                    SSLCACertificateFile $webdirdest/management/other/ca.cert.pem

                    Note the end of the line is also changed!! Then restart the webserver (systemctl restart httpd).

                      The result is the same:
                      on the client the message error is again
                      “Communication ERROR: SSL connection error: System.Security.Cryptography.X509Certificates.X509ChainStatus[]”
                      and on the server nothing is logged.

                        I thought you see the HTTP 302 redirect on the server?!?

                          No, there is not the 302 redirect in the log. It’s as if the server receives no demand from the client.
                          I don’t find the IP address of the client in the other files in /var/log/httpd.

                            Ahhhhh, sorry, I must have overlooked this was only from when you installed the fog-client.

                            I have searched the web for this error but haven’t found a clue yet. I will try to set this up and see if I can replicate the error.

                              @adrien17 Ok, I was able to replicate, find and fix the issue. Arrrgh, should have looked into this before pushing out the new fog-client release yesterday. I knew 0.11.18 wouldn’t be bug free but didn’t think we’d catch one that quickly.

                              Download fixed DLL and put in /opt/fog-service/Zazzles.dll. Then stop and restart the client or reboot the computer.

                                Okay, now the client gets the information from the server without error and can execute a task launched from the server.
                                Thanks a lot.
