Yomichan Issues
Audio download failed due to possible extension permissions error (Chrome)
Depending on the extension's configuration, Yomichan can sometimes run into issues with downloading audio files while creating Anki cards. This may be due to a permissions issue where Yomichan hasn't been granted access to the sites hosting the audio files.
Check the Site access section of the extension settings pages and grant the extension access to all sites or add the specific audio host URLs.
Audio download was cancelled due to an idle timeout
Audio files can be downloaded from remote servers when creating Anki cards, and sometimes these downloads can stall due to server or internet connectivity issues. The Idle download timeout setting on the settings page specifies a time limit for stalled downloads.
