Hi Xiao Cao,
I encoutered the same issue with this version of the SFTP module in Mendix 9.
What did the trick for me, was to first set ‘Strict host key checking’ to Yes. Then, obtain the host key by cling the button ‘obtain host key’ and retrieve this key. When this is done, set the boolean ‘Strict host key checking’ to No again. Then try to connect again. This solved the issue for me. I hope it's helpful.
Cheers,
Justus
Hi Xiao Cao,
We also faced this problem recently and solved it by deleting SFTP configurations and readding them again. You get option to obtain host key which you can use during authentication.
We decided not to use key and its working for us as expected with normal username/password.
Thanks,
