FTP with TLS - SSL: Loaded, but libeay32 was already loaded from: D:\WINCMD\addons\FS\sftp\libeay32.dll

[tmcdos]

I am using the SFTP plugin 2.70 with a 32-bit Total Commander 10.51
I have a stored FTP account whose flag SSL/TLS is enabled.
Normally, I have no issues connecting through this FTP account over TLS:

Code: Select all

Using sChannel (Secur32.dll) for SSL/TLS connection.
Connect to: (25.10.2022 16:30:44)

However, if I connect even once by SSH/SFTP (using the SFTP plugin) to any server (it does not matter which server) and then disconnect from SSH and try to use the above FTP account over TLS then I get a weird error from Total Commander:

Code: Select all

SSL_read returned -1, SSL_get_error=1

and connection fails.
And I have to quit Total Commander before I can connect with FTP over TLS.
Any workarounds ?

You either need to remove the openssl dlls from the plugin directory and move them to the Total Commander directory, so both functions can use them. Or explicitly disable openssl for the internal FTPS function:

wcx_ftp.ini
[General]
PreferOpenSSL=0

Thanks, disabling OpenSSL fixed the issue!
