What error do you get when making the request over port 21?
The error is "FTP info: connect to xxx.xx.xxx.xx port 990 failed: Timed out
FTP info: Failed to connect to hostname port 990 after 21047 ms: Timed out
FTP info: Closing connection 0
FTP/FTPS/SFTP transfer error: Timeout was reached".
I think the problem is the combination port 21 and implicit.

Based on the above you're trying to connect over port 990 but you're saying its only open on port 21?
What port are you specifying for the URL?
Sorry, my mistake.
I tried alredy also port 21 and the error is:
"Using explicit FTPS for hostname 'hostname' because the URL protocol is ftpes, or because the protocol is ftps and the port is 21
FTP info: Trying xxx.xx.xxx.xx:21...
FTP info: Connected to hostname (xxx.xx.xxx.xx) port 21 (#0)
FTP info: server response timeout
FTP info: Closing connection 0
FTP/FTPS/SFTP transfer error: Timeout was reached"
In FTPCaller I can't switch the method from explicit to implicit.
FTPCaller uses automaticly explicit as metod with ftps:// and port 21.

You may need to look at using something like python to make your requests in this instance. It may also pay to submit a suggestion to allow the manual override of the ex/implicit - https://community.safe.com/s/bridea/acideasULT__brIdea__c/00B4Q00000AWlEVUA1
Sorry for late answer!
We solved the problem as we changed the protocol from ftps to sftp.
FME works fine with sftp.
Thank you for your support.
