Bug description

Upgrading to 32.06 appears to have introduced a "port" field for SFTP External Storage connections which broke existing SFTP connections with custom ports until the port number was migrated from the hostname field (IP:PORT) to the port field.

This caused directory listings which include SFTP External Storage locations to fail to display in Files with a vague error.

The cause of this problem was not clear from the logs, so I am documenting it here in case anyone else encounters the same problem.

Steps to reproduce

1. Upgrade to 32.06 with SFTP External Storage with a custom port in the hostname field (IP:PORT)
2. Fail to load Files locations when SFTP External Storage is involved

Expected behavior

1. Upgrade to 32.06 with SFTP External Storage with a custom port IP:PORT
2. See Warning message in Administration that recommends migrating the port number to the new field

Probably related to #57793
Maybe you can revert it (it's a single line of code) and test?

To solve this, you have to add the SFTP-Port in the External Storage Configuration. There is a port-Field under the Host-Field now. Just enter the port number (22, 23 or whatever your SFTP port is), and everything will work.
But of course this should not have happend. Users should not have to change configuration manually on updates.
Is there a possibility to extract the port-numer from the host-field and enter it in the port-field?
