FTP connection broken, empty window, no content, no parent directory
Posted: 2020-08-26, 13:09 UTC
Since few months I'm experiencing an issue with FTP connection on TC 9.51 (64bit). It is broken a "funny" way. When connecting to the FTP server, it asks for credential (TC administrator password), but it gives an empty window (even the parent directory ".." is not displayed). No error message is displayed. Repeated reloading of the directory and connection list the content of the directory. The bug is not regular, is occasional.
Below I could catch logs two connections one after the other in tcftp.log. The first one showed the empty window. The second connection loaded the complete content of the directory. What can be the cause of a half-way "broken" connection? The FTP server support on the other side is clueless.
