Description of issue:
Suddenly pushover notifications stopped working on download. They are still working on grab.
I don’t know if it’s relative to the issue but I cannot select “on rename”, it’s greyed out.

On Rename is when files in the series folder are renamed. On Import is what you’re looking for, but it’s failing because Pushover is closing the connection for some reason; not sure why grab events would be fine.

When I test the connection it’s working fine.

Yesterday I had the same issue on grab too. Today I received notifications for downloads. So I guess it’s appearing randomly.
