Description
Hello
FileZilla 3.24
Server Windows 2008 R2
IIS has self-signed certificate for internal usage.
I always get the error:
GnuTLS error -48: Key usage violation in certificate has been detected.
Could not connect to server
Filezilla 3.23 (and above) works fine without problem.
How can I fix it? where can I find old versions of FileZilla
Note:
See TracTickets
for help on using tickets.
This is a problem with your server's X.509 certificate chain: Either the server certificate itself or another certificate in the chain has a key usage restriction that is violated. For example a certificate with a key usage restriction to only allow cert signing cannot be used to authenticate TLS connections. See section 4.2.1.3 of RFC 5280.
You need to contact your server administrator or server hosting provider for assistance to have the server's certificate replaced.
