Internet stranger, I cannot thank you enough for this.

I agree with @bmcahill . This code was like a miracle!

Thank you so much!

It's work! Thank you. You save our life.

Oh my god... sir, you can't even imagine... this is pure gold, thank you so much!

Hello,

I'm not a python expert, I've been looking for days how to connect to FTP with TLS implicit on port 990, and there is no way. I've been searching and trying many things without success and I found this page, so thank you first of all.

Forgive my ignorance, but what should I add to this code to run it in my ide and see if it works with the FTP server I want to connect?
Thanks!

@Niilavarnam Hi, this is just a class code that will replace the original one to enable implicit TLS. Connecting and other logic are up to you how you will manage it. For example:
ftps = ImplicitFTP_TLS()
ftps.ssl_version = ssl.PROTOCOL_TLSv1_2
ftps.connect(ftps_host, ftps_port, timeout=30)

It works!!! I will cry, you have saved us, we are grateful

Worked for me. Thank you for saving me so much time, I was in a very deep rabbit hole without this. Thank you!
