A few months ago I created a FTP connection for one of my flows and everything was working perfectly. Now the flow using this connection started to present an error. When I tried to create the connection again, I started to get this error: "Unable to connect to the remote server: 'ftp.XXXX.com.br'. Please verify server logs to troubleshoot connection issues".
I've whitelisted all the possible IPs Flow might be using, considering the environment region I'm using.
One test that worked only once was to create a new environment with a different region. In this case Flow was able to connect to the FTP server at the first time. Although, when trying to reconnect, it didn't work anymore.
Does anyone have been through this issue or have any clue on how to solve it?
