SFTP error

Help & Support
1

I have an SFTP site setup which I had been using regularly with no problems but have not visited for several months. When I tried to access it today I got the following error in the FTP log:

Opening Connection ssh.eu.pythonanywhere.com:22
Server version: SSH-2.0-OpenSSH_8.9p1 Ubuntu-3ubuntu0.10
Using SSH protocol version 2
We claim version: SSH-2.0-PuTTY_Directory_Opus
Couldn't agree a host key algorithm (available: rsa-sha2-512,rsa-sha2-256)
SSH: Fatal: Couldn't agree a host key algorithm (available: rsa-sha2-512,rsa-sha2-256)
Connection closed

I am using the latest version of DOpus (13.11 64 bit on Windows 11).

Any help appreciated.

Thanks.

It likely means the server side has been updated/reconfigured and no longer accepts the encryption methods the current SFTP code in Opus understands.

We'll be replacing the SFTP code with a newer library in the future, which will fix it.

Ok - any timeline on the SFTP update?

Thanks.

Hi.

I've just run into the same problem with a new server I need SFTP access to. The last request for a status update in this thread was 6 months ago, but there was no reply. Can you please let me know when this will be fixed, as it's now hampering my ability to manage this server efficiently. I know I can use FileZilla as an alternative, but that's a very clunky workflow compared to using Opus for everything. Given that we've paid extra for the Advanced FTP feature, it would be appreciated if fixing this issue could be made a priority.

Kind regards,
Mathew
