Issue: Error using Aspera to download SRA files with Kingfisher get

I'm encountering an issue while trying to use Aspera to download SRA files via Kingfisher get. The command I ran was:
kingfisher get -p PRJNA504891 -m ena-ascp ena-ftp prefetch

However, I am consistently getting the following error:

However, regular downloads without aspera seems to work fine.
Any guidance or suggestions on resolving this issue would be greatly appreciated!

Hi,

My suspicion is that there is some issue with your ascp install. Has it ever worked?

Downloading that run works fine for me:

$ kingfisher get -r SRR14018896 -m ena-ascp

Hi,
Thank you for the suggestion.

I will re-check the installation as aspera has never worked.
