  • Having an issue with connecting with explicit FTP over SSL.

    It works in passive mode in plain FTP, however when i try to configure for explicit FTP it is unable to get past the passive mode.

    It gets stuck in passive mode forever when I do not do plain FTP. I have configured the ports 21, 990, and 50000-51000 in both my network and computer firewall.

    I have read articles about NAT firewalls and it may apply to me, but I have configured my network with filezilla to work on my external IP and on the custom port 50000-51000. A popular article on this topic is https://www.elitehosts.com/blog/php-ftp-passive-ftp-server-behind-nat-nightmare/ which seems to apply to me but I am unsure if I am able to do anything on my end at the server.

    I’ve tested this on ftptest.net which returns positive for passive mode and explicit TLS.

    If a mod could fix the 2nd last line that would be appreciated too

    There nothing in the last 2 lines that need fixing that I can see.

    Also FTP or FTPS (The STARTTLS fails with most firewall controls) is an E-V-I-L protocol. Any chance you can use sftp with this backup plugin?

    Thank you for your reply

    (207,x,x,x,195,185) was something i forgot to censor.

    I don’t have any sftp server setup.

    It’s an IP address and that’s not something that gets edited out. There’s no point as it doesn’t represent any sort of risk.

    Edit: But as I did see something else there that WAS sensitive, I did remove that part. Careful posting logs in the future.

    I have the same issue. Backups aren’t working since a week. How can I solve this ?

    I can upload files to the FTP server from other FTP clients, but BackWPUp plugin has this error. ??
