Hello
https://issues.apache.org/jira/browse/CAMEL-17835 issue was about switching
from unmaintained version of jsch to new forked version with more (safer)
alogorithms supported (like SHA2 and eddsa).
You'd have to enable server side and Camel debug logging to check which KEX
algorithms are presented by Camel and which are offered by the server.
kind regards
Grzegorz Grzybek
