Hello,

A client of mine is encountering this connections issue and I am not able to replicate. I use the same version of WinSCP and am able to logon to the ftp server using the same credentials they are using.

WinSCP info

Code:
Remote system = UNIX emulated by FileZilla
File transfer protocol = FTP
Cryptographic protocol = TLS/SSL Implicit encryption, TLSv1.2
Encryption algorithm = TLSv1/SSLv3: ECDHE-RSA-AES256-GCM-SHA384, 2048 bit RSA, ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AESGCM(256) Mac=AEAD

Compression = No
------------------------------------------------------------
Certificate fingerprint
*removed*
------------------------------------------------------------
Can change permissions = Yes
Can change owner/group = No
Can execute arbitrary command = Protocol commands only
Can create symbolic/hard link = No/No
Can lookup user groups = No
Can duplicate remote files = No
Can check available space = No
Can calculate file checksum = No
Native text (ASCII) mode transfers = No
------------------------------------------------------------
Additional information
The server supports these FTP additional features:
  MDTM
  REST STREAM
  SIZE
  MLST type*;size*;modify*;
  MLSD
  AUTH SSL
  AUTH TLS
  PROT
  PBSZ
  UTF8
  CLNT
  MFMT
  EPSV
  EPRT


The following is the WinSCP log

problem caused by firewall? the opening connection for listing of "/" followed by connection closed versus the one session where the connection opens and the list is transferred is interesting.

Is the client able to connect with any other FTPS client?

They tried Filezilla and it also failed. This prompted them to check their firewall again. They were able to view their directory once they made the appropriate changes to the firewall.

Issue closed. Many thanks.
