Hello,

I'm trying to setup a sync to an FTP. But when i try to select the folder to sync, FFS returns the following error:
Der endgültige Pfad für "[redacted - FTP server URL]" kann nicht ermittelt werden.

CURLE_COULDNT_CONNECT: Failed to connect to [redacted - FTP server URL] port [redacted]: Connection refused [curl_easy_perform]
If i try to do the same with Filezilla, it informs me that the server has an unknown certificate issued by "Sectigo RSA Domain Validation Secure Server CA" - probably not an official source(?)
The validity-date-range is form 2019 to 2021

So my question: Is this due to the same error? AND is there a setting where i can tell FFS to accept "unknown" certificates?

Best regards and thank you for your feedback in advance
