I have a system that uses FTP to run backups. This has worked well for about 2 1/2 years running it's daily backups. On 2/8/24, the backups stopped and it is blaming bad credentials. The credentials have not changed, nor has anything on our local network. I have confirmed I can connect to the NAS using those credentials. I installed FileZilla on both my machine and the machine running the application that is being backed up. From my machine, using FileZilla, I am able to make the connection without issue. When I run FileZilla from the machine running the application, I get invalid credentials when I try the FTP connection. These are both Windows machines.
So how can credentials be correct from PC1 but invalid from PC2 when connecting to the same NAS?

Re: Invalid Credentials From One PC
As a solution, I present a famous haiku:
It's not DNS
There's no way it's DNS
It was DNS
The app developer suggested a DNS change to fix a certificate issue. This change broke the machines ability to access the internal NAS. I tried via IP and it worked, so I undid the earlier DNS change that was also not the solution to the certificate issue. All good now.
