Probably you need a setting
URL = https://elog.test.km3net.de
or so in your elogd.cfg file. |

Thanks for the quick reply! Sorry, I forgot to paste the "global" part of the config, I have that URL already set:

I also tried the default configuration (example config) and it that works behind the load balancer. So I guess it's related to the password-page,
which causes this redirect loop? Our logbooks are all password protected, so when a logbook URL is clicked, it should first present the login-form, and
that's where it chokes. |

Yeah, after you enter a password, elog redirects to what it finds in "URL". You can trace that by opening "development tools" in
Google Chrome, go to "network" and watch packets going back and forth. I never worked with the load balancer, but maybe you need a different
"URL" containing a '/' at the end? |

My problem is that I don't even reach the page where I can enter a password. If you go to https://elog.test.km3net.de and click on a logbook,
you'll see that it immediately goes into a redirect loop. I already logged the routing but there is nothing else...

Attached is the log, where you can see that `Operations+IT` redirects to `Operations+IT/` and that redirects to `Operations+IT` again, which then goes
to `elog.test.km3net.de` and `Operations+IT` again etc. etc.
EDIT: I use the very same load balancer confugration for dozens of other services incl. Apache, Nginx, GitLab, Mattermost, RocketChat |

Yes I see the redirects. You say with the example logbook it works, right? Is it the password protection which triggers the problem or anything else?
Does it work if you take out the password protection? The key is to identify which setting in your config file triggers the problem, so you can bracket
the problem down between the example logbook and your logbook definition. |

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 |
