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

I use an iPhone 14. I often use the hotspot feature to connect to an external ftp server, but after the V17 update, I can't connect to ftp when connecting to a wireless hotspot. However, I can connect to ftp when using a wired hotspot. Please note. I think it's a V17 bug. I was using it normally in the previous version.

Exactly the same situation. I'm also a photojournalist working for a news agency and getting the images on my client's server fast is my top priority. The last champions league match i did was a nightmare because of this issue. It has to be related to the iOS 17 update because it was the only thing that changed since the last soccer game i did. Please fix this ASAP! My job relies on fast transmission.

Same here. FTP is broken in iOS17 hotspot.

I tether my iPhone to a Canon EOS R3 using the personal hotspot to send live news images directly to the newspaper picture desk and this is broken as of the latest iOS update.

I am sorry that this causes problems but I have to say that something is very wrong when an IT department in this day and age requires you to use a protocol has no encryption and is a horrendous security risk. Do they also login remotely using telnet? Like telnet was abandoned (and rightly so) years ago, and so must ftp. A public server using ftp is just irresponsible.

9 in 10 photojournalists uses ftp to transmit their work

That may well be true, but it says the the news agencies or whatever entitities require that are grossly incompetent or even criminally negligent. From the point of view of a server it is perfectly trivial to implement a proper secure protocol; and from the client it is just a matter using sftp:// instead of ftp://

In case people are not aware: ftp sends user names and passwords in plain text. Think about it for a second.

Bug Tracker form but requires a free Apple Developer account, otherwise use feedback on iPhone. Have already done this but helps if others also report the issue. https://www.cultofmac.com/820395/file-bug-report-on-iphone/

I can't convince my clients to change something they're been using for years without any issues. For what i've been reading last days if Apple doesn't come out with a solution fast, the only way to solve this is downgrading to iOS 16. It's what i'm planning to do.

Maybe not, but you should try. It is your data on(the)line, too. ftp is so unsafe that it's creepy. Ignorance may be a bliss, until it isn't.

Ask them to post the login credentials on their web site. Seriously. That’s what they are effectively already doing.

Any file server with known credentials too often ends with myriad files on their server that are illegal to even possess, and with the ensuing legal hassles.

If they’re insistent, insert some text in your contract that makes it clear that you’ve warned them and this is their mess, so you are less likely to get blamed for any resulting illegalities.

PS: sftp also avoids ”fun” with firewalls.

Hello,

another photojournalist here, trying to upload over ftp sharing the internet from my iPhone but it just does not work!!! For me, it used to work, and then stopped before I updated to iOs17. Then I updated thinking it would start working, but nothing. My friend shares connection from his iphone 11 iOs17 and it works? It just does not make any sense. Hope someone finds a solution fast.

I just gave up. Apparently Apple is in no rush to fix the issue, and are busy passing the buck to the carrier, the ftp client, anything but iOS 17. So I reinstalled iOS 16. And AMAZINGLY everything works now! So, until I see that iOS 17 is fixed, I’ll stick with what I know works.

This is definitely something in iOS 17 that is blocking Port 21 for FTP over Hotspot. As others have said - it’s not a Carrier issue!

I can use a VPN on a laptop via hotspot and that worked - but does no good when I’m trying to connect a camera like Nikon Z9, or others.

what’s the best way to file copious amounts of bug reports with Apple?

FTP might be old tech, but it’s still tech we need for photographers.

Same here. 100% ios17, I tried with multiple devices, multiple phones, multiple contracts with the same carrier, multiple connection methods (BT, Wifi, usb)

Whenever there is ios17 is involved, it doesn’t work.

Wish I could go back to ios16 because of this issue.

ios17 won't work on my 13 Pro Max (Telus), but a friends 13 Pro with ios17 on Bell worked as a hotspot for my ftp to either my Mac Studio or MacBook Pro. I tried his SIM card in my phone and my phone still wouldn't work. The only way I was able to upload images when I was working remotely via my phone was to airdrop the images from my laptop to my phone and use the iOS app "FTP Manager" to upload to my company ftp. In the meantime I rolled my phone back to ios16 just to be sure and it worked without issue.

And yesterday a photo agency told their photographers the following:

"We wanted to bring to your attention an issue we are seeing with Apple iOS 17.x.x

Unfortunately, it appears there has been a block to FTP servers using the mobile hotspot feature from Apple iPhones. This has been tested connecting with both IP & DNS

The issue appears to block FTP connection once getting to the last step in the configuration process."

I have the same problem.

FTPs work well by connecting my MAC on WIFI mode but by Hotspot mode, after updating to IOS 17 my iPhone, don't work at all. FTPs connections go to timeout.

I need to fix it or I can't work at all.

if someone have a good solution just tell me.

Thanks a lot!
