Connection to server takes 10 seconds in FTP mode and port changes don't work

[msbt]

I'm currently testing the SFTPGo app and ran into a few issues:

1. When trying to connect to the FTP server (not SFTP, that works fast as expected), the connection is stuck for 10 seconds at Connection established, waiting for welcome message..., which is getting boring real quick, when you transfer files with separate connections, every action will take another 10 seconds because a new connection is getting established. Single connection mode works fine after the initial connection has been established.

Status:	Connecting to 123.123.123.123:2121...
Status:	Connection established, waiting for welcome message...
[10 second break here]
Status:	Initializing TLS...
Status:	TLS connection established.
Status:	Logged in
Status:	Retrieving directory listing...
Status:	Directory listing of "/" successful

Unrelated issue: Changing ports doesn't seem to work, I tried both, SFTP and FTP port and they both only work in the standard setting (2022 and 2121 respectively), no connection possible after changing the port. The config file looks fine, but nothing's going through.

Hello @msbt
Thanks for reporting, we will have to look into it.

Hello @msbt
I can confirm that the waiting for welcome message is indeed slow for ftp.
Also figured out the port change issue.
Working on it.

Hello @msbt
An app update will soon be avaible that fixes this issue.

@james thanks, just tried, the port issue is resolved, thanks The connection delay is still there though, you think it might be worth reporting upstream?

No. I've tested this on another SFTPGo instance that is outside the Cloudron ecosystem, and it worked with no issues.
So I must assume we have a mistake somewhere.
