When downloading some, but not all, nightly builds from https://www.igniterealtime.org/downloads/nightly_openfire.jsp, a "403 Forbidden" response is returned.
This problem affects RPM builds that were generated on April 30, 2019, and later.
The file permission mode on the affected files was 640, while other files are 644. I'm unsure what caused this.
I've modified the "copy to website" script of these plans in Bamboo:
These scripts now use rsync, instead of scp. rsync can take an argument that explicitly sets the file permission mode, which I've set to 644.
I've manually set 644 to older, affected files.
