Yes, I used the empty `passwd` file from example. When I then click on one of the logbooks, I get to the page where I can register a user (see attached
screenshot). After clickin on "Save" for the user registration, I again get the redirect error. Once there is a registered user (i.e. a
non-empty password file) the redirect issue is persistent. Any idea where the problem might be? I just emptied the password file again, so you can |

The issue is still present and now it's quite urgent to move this last service into the Swarm. Does anyone maybe have an idea what's wrong? To
sum up: if there is a non-empty password file, the login page chokes in an infinite loop of redirects. I am using the same HAProxy load balancer configuration
as for all the other services (running Apache, NGINX, GitLab, XWiki, etc.): |

Invalid Content-Length in header when running behind a load balancer, posted by Tamas Gal on Wed Jan 25 14:36:33 2023

I am still struggling to get ELOG running behind a load balancer and hope to get some advice here. As already reported in https://elog.psi.ch/elogs/Forum/69542 I
observed an infinite loop of redirects when prompted to log in and using a non-empty password file. Without a password, the service worked as
expected. This was with version 3.1.3. |

Upload via command line through Apache reverse proxy and load balancer, posted by Tamas Gal on Wed Jan 25 18:41:27 2023

After fiddling around I managed to get ELOG working behind the load balancer HAProxy by stacking ELOG together with an Apache reverse proxy in a Docker
stack. I am currently pretty convinced that something with the HTTP communication is somehow faulty in ELOG and Apache is more forgiving than HAProxy,
since the configuration is the same as without Apache. So putting ELOG behind an Apache and then Apache behind the HAProxy is working. |

I put the ELOG service behind an Apache reverse proxy which is now sitting behind the HAProxy. It works like this, but it's just a workaround. I
am pretty sure that ELOG has problems to communicate with HAProxy correctly and it seems that Apache is more forgiving. So that the chain HAProxy ->
Apache -> ELOG and vice versa is working. |

The problem was resolved. I forgot to do this statement...

Because elogd uses links to itself (for example in the email notification and the redirection after a submit), it has to know under which URL it |
