Hi All,
I have been using wwFTP for a while now. I use the FTPSendFileEx() function to upload a simple .csv file. The process has worked well for months.

The upload started failing on Monday. I can still connect to the server via FTPConnect(). Also, I can successfully upload to the server via the command prompt using the login credentials.

However, when I try to upload the file using FTPSendFileEx(), it fails and oFTP.cErrorMsg contains:
200 Type Set to I
227 Entering Passive Mode (10,9,103,31,201,38)

I tried setting oFTP.lPassiveFTP = .T. but it still failed. Does anyone know what this can be? Nothing on the client changed. Is there something that could have changed on the server? The vendor said there were no changes on the server.

TIA,
Steve

OK, the vendor had made some sort of change to their firewall that was causing the issue. They called it Packet Inspection rules. Anyway, it's working again.

Thanks,
Steve
