Can you ping them?
Can you start up a 5250 session on them?
If you start up a session try this command:
WRKREGINF EXITPNT(QIBM_QTMF*)
8=Work with exit programs
If there are any programs here then someone installed an exit point
program and you now have to be approved.
The other possibility is that your firewall team just cracked down and
each incoming address has to be approved. We tried that and quickly
abandoned it. With a mobile workforce it was too fluid. Actually it was a
MAJOR customer whose purchaser was doing ordering while at night classes
that put the kibosh on that.
Another possibility is that your coworker is using SFTP or FTPS and you're
using plain FTP and they cracked down on that. We used to allow ftp
traffic from the internet and have since shut that down in favor of SFTP.
We still allow ftp for outbound though.

Subject: Is this happening to you?
CAUTION: This email originated from outside of the organization. Do not
click links or open attachments unless you recognize the sender and know
the content is safe.
Suddenly, I can't use ftp from my PC to any of our servers.
I get a 425 (not able to open data connection).
I am remotely connected via VPN to our corporate network.
But a co-worker, who is similarly remotely connected, can use ftp to our
servers without problems.
Nothing has changed on our servers (except a cache battery replacement
on one of them).
Nothing I know of has happened to my Windows 10 PC.
The only thing I can think of is that the Norton Anti-virus product on
my PC (it came free with our internet provider),
has been replaced with something that supposedly provides the same
protection through my router.
Further, we have applications that use Scott Klement's SMTPR4 code and
they all fail when they try to send email through our servers as well.
Here's that error...
ERROR: connect(): A remote host refused an attempted connect operation.
connect(): A remote host refused an attempted connect operation.
Why would requests from my PC to the server be rejected or fail, but the
same requests from another PC in another location work fine?
I've tried using the passive mode to no avail.
