Unable to connect to any device since macOS 18 release:

Since adopting macOS 18 CyberDuck is unable to connect to any device via FTP on a network. (No offense, FileZilla has no issues but your product is far superior!).

I reverted back to macOS 17 and have had no issues. The error in the screenshot happens to all bookmarked IPs and any new IP addresses added.

See attached screenshot.

Can you verify that Cyberduck has permission to access local network?

I'm having the same issue. I'm on macOS Sequoia 15.1.1 and latest version of Cyberduck. Cyberduck has permission to access local network. I installed Crossover and installed WinSCP and am able to connect to sftp and ftp locations. After WinSCP connects, then Cyberduck usually connects to sftp.

Please try if changing the following settings resolves the problem:

• Disable firewall in Settings → Network → Firewall
• Disable any active network filter in System Settings → Network → Filters
• Set System Settings → Wi-Fi → Details → Private Wi-Fi address → Fixed

Yup. This fixes it. Back on Cyberduck and happy as heck ^_^

No. Firewall is not enabled on my computer.

Can you check if there are any network filters enabled on the system visible in System Settings → Network → Filters.

[TownerFiltration]

The System Settings → Network doesn't have Filters listed at all. Would they be in something else?

Here is a follow up for anyone having this problem. macOS Sequoia added a Private Wi-Fi address function. I noticed it while trying to remote into the computer trying the IP address that was assigned to the computer and finding out it had a different IP address. I turned off Private Wi-Fi address and Cyberduck started working fine. Next day and it is still working fine. Hoping it stays that way.
