Error when running FTP object

When trying to test a package, my package throws an error (see attachment). The file is zip'd but is rather large. I am continuing to test but did not know if this was an known problem. I am running the 64 bit version 6.4.3.9. I have to kill the application as if I click Ok to clear the error it returns after uploading about 300KB. The zip file size is 2.34 GB so it is rather large.

Can you confirm that you are able to upload the file using filezilla?
It can be FTP server limitation

Status update: we have reproduced the problem:

BTW 32bit version is working fine

Thanks Mike, Does this seem to be something you will be putting a Patch out for quickly or should i back up all my items and install the 32 bit version?

If you are are using an agent for execution you can run the package in 32 bit mode.
When you schedule it for execution select 32 bit.

We will let you know once an update is ready.

Hi, I changed to run as 32 bit, however, I am now getting the following error. Do i need to add something for the 32 bit to run correctly? Error 06/05/2019 10:01:37 AM Following Ftp Error happened Could not load SSL library.
