The Transfer Manager window of Aspera Connect shows the error:
Error - FASP1 support not installed
This error is caused by a web application requiring support for the FASP v1 protocol (either intentionally or by mistake). Aspera ended support for FASP v1 in 2009. This is a problem with the way the web application was written, and not a problem with the Connect browser plug-in or the Aspera Server used by the web application.
If you are the web page developer, add
v=2 to all fasp:// URLs in your application for both uploads and downloads. In the event that you are still using a FASP v1 server, contact Aspera support for an upgrade at firstname.lastname@example.org. Aspera ended support for FASP v1 in 2009.
If you are an end user experiencing the error, please contact the server owner or developer and point out this article.
