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

I need to connect to my webserver via FTP from my MacOS (13.4.1). When I'm connected via home internet provider, everything is OK. But when I connect via hotspot from my iPhone (iOS 17), I can't connect to FTP. The error message is "Connection timeout". The Internet in web browser is working perfectly, but FTP connection doesn't work. I tried several FTP clients (Filezilla, Forklift, ...), but still the same problem. 

 

A few weeks ago, I used this FTP clients without any problem with hotspot, so maybe it could be related with iOS 17 update. 

 

Has anyone same problem? Is there any possibility to analyze network settings to find out where could be the problem? I tried to switch off the Firewall on MacOS, but no change...

 

Thanks.

iPhone 13 Pro, iOS 17

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 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...
