Can't connect to FTP server when I'm connected via hotspot

Hello, this is an IOS 17 problem. In other forums, users report the same error. In Germany there is now IOS 17.0.3 and the bug is not fixed yet. The only solution at the moment, if you have an old iPhone, is to use it with a previous version. I use my IPhone 7. However, the constant map change is annoying.

I gave up with Apple on my iPhone 13 Pro, and reloaded iOS 16.7. And to Apple's loss, I normally update my phones every other version But with this problem, I'm not about to spend money on a new iPhone 15 Pro that I know will be unusable for ftp transfers. And even if and or when they get it fixed, I'm in no hurry to update my phone. I truly cannot believe how Apple isn't recognizing this issue, and why there isn't more out there on people and this issue.

I've been an Apple user since 1984, and have never seen Apple stick their heads in the sand so deep on this MAJOR issue...

Temporary solution is using a VPN software. Somehow it works for me to connect to FTP servers over VPN (such as NordVPN). I hope it will be really fixed with the new IOS, because it's super annoying and doesn't work no matter which provider/mobile network I'm using.

I have exactly the same issue. Some days ago everything was working fine using FTP on my Mac being connected via hotspot to my iPhone 11. Now only timeouts no matter what FTP client. I didn’t check from Wifi though. Hope that works. But pls fix this issue Apple! iOS is 17.0.3.

I know is not the solution but it works.

Same work, same problem!

9 in 10 photojournalists uses ftp to transmit their work

We will need to file a bug report as Apple don't monitor these forums.

It's 100% an Apple iOS 17 bug affecting FTP on port 21 over Personal Hotspot connections.

I would look into what port is being used many ftp servers do not use port 80

Checking TCP/UDP ports! - Apple Community

could be something changed no longer allowing the port the ftp rely on access

iOS 17 with hotspot impossible connect to… - Apple Community

Do you have to add the app to Full Disk Access...(?)

I did it now but nothing changes.

I would like to remind you that to all of us up to iOS 16.x everything worked wonderfully. Everything changed with the update to iOS 17

Everything doesn't work when tethering with ios17 and ipados17.

FTP connection can be made correctly using tethering with Android smartphone, iOS16, iPadOS16.

The problem is with the 17 series.
