I think it's helpful to provide more context and actually also provide the suggestions that had been given. In https://suse.slack.com/archives/C029APBKLGK/p1651500641607249?thread_ts=1651492403.781139&cid=C029APBKLGK

kraih explains that the recurring polling is coming from old jquery code https://github.com/mojolicious/minion/blob/33644624fc62013186fe0808d3365ad5fd8ce347/lib/Mojolicious/Plugin/Minion/resources/public/minion/app.js#L24

app.js
function pollStats (url) {
mojolicious/minion | Added by GitHub

this can be considered to be changed.
Also Andrii Nikitin already suggested: "It might be even safe to just allow minion/stats without authentication, at least something which can be done in openqa without changing the minion lib"
to which kraih confirmed: "yes, the route has a name, so it can be reattached somewhere else in the routing tree https://github.com/mojolicious/minion/blob/33644624fc62013186fe0808d3365ad5fd8ce347/lib/Mojolicious/Plugin/Minion/Admin.pm#L22

Admin.pm
  $prefix->get('/stats'   => \&_stats)->name('minion_stats');

first to reproduce the issue what I did was to start a bare openQA instance with config httpsonly=0 in etc/openqa/openqa.ini of my openQA working copy and keeping everything else in place. Then started sudo -u geekotest env OPENQA_BASEDIR=/tmp/tmp.n0KbC5PDt2 script/openqa-webui-daemon with /tmp/tmp.n0KbC5PDt2 being a directory owned by geekotest and an empty subdirectory db to prevent an error about unable to create a lock file. Then I went to http://127.0.0.1:9526/ , logged in, then to http://127.0.0.1:9526/minion/jobs in my browser, opened developer tools, "Network" tab and saw a request every couple of seconds to "stats". I opened http://127.0.0.1:9526/ in a second tab, logged out and could see that the requests in the developer tools go to "www.opensuse.org/openid" instead.

Could fix it with the help of kraih

PR merged. I am sure that no one currently has a tab open for an not-logged in openQA instance showing minion jobs so I guess we can immediately resolve :)
