Troubleshooting the Underscore Folder
The two most common causes of access problems with the _/RemoteServers folder are expired authentication and credential permission restrictions.
Remote Server Cannot Connect
If a remote server's authentication expires or is revoked, the corresponding underscore folder cannot connect. Re-authenticate the Remote Server to restore access.
Cannot Access Root of FTP or SFTP Remote Server
If the credentials for your FTP or SFTP remote server only allow access to a specific subfolder rather than the root, the underscore folder cannot connect. Most FTP and SFTP clients work around this by letting you connect directly to the subfolder, but the underscore folder always connects at the root. Use a Remote Mount to access the subfolder those credentials can reach.
