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
