dnf issues, where to report please?

Fedora 34. Just ran sudo dnf -y update. A message flashed past, too quick to catch. On reboot, no name resolution. 1. Is there a dnf log please on Fedora? Location? 2. Where should I report dnf issues (or Fedora? not sure) Any help appreciated. TiA -- Dave Pawson XSLT XSL-FO FAQ. Docbook FAQ.
