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

No, it's FTP server at commercial web hosting company, not in my home network. I have more web hostings in various companies and the problem is the same.

I'm trying to connect via domain name, but I've also tried to connect via IP address. Still timeout...

Thank you

FTP is NOT for going across a network that is incredibly irresponsible! If you want to go across the network you should be using SSH!

I managed it now via copying the zip via airdrop to my phone (iPhone 13pro) from which I could upload via an ftp app… annoying like that….

How do you do it? I contacted the technical support, but after an hour of conversation and a lot of testing, they said that the problem could be with the developer of the ftp client software.
