Access denied

[eceyagman]

I had no problems accessing our remote server via SFTP, but after upgrading to Sonoma today, I get the following error when trying to connect "Access denied Operation not permitted. Please verify disk permissions." However, I can open it in Terminal and access the shared folder there. Can anyone help with troubleshooting?

Thank you!

The mounting process failed as the macOS upgrade changed the privacy settings, causing the custom mount location to be inaccessible.

I have the same issue, after buying Mountain Duck via App Store.
I grant full disk access for Mountain Duck, but it doesn't solve the problem.
I can't change Mount location also:
