Foreman » Smart Proxy

Problem:
The TFTP copying of vmlinux and initrd fails with "url malformed".
The Target URL itself is validated muliple times with curl and wget manually, so the file is really downloadable. The source is an extracted OL8full ISO to /var/www/html/pub on the same foreman/katello host. Please see attached LOG File.

Expected outcome:
vmlinux and initrd are put into /var/lib/tftp/boot

I believe https://projects.theforeman.org/issues/36138 introduced a new bug. If i remove the "file" part from --time-cond the download works as before.
