Hi,

I'm using Lazarus 2.2.4 with Laz_Synapse. I'm hosting a website on
000webhost.com and I need a FTP connection that can be used by other
users then myself. I've tested the connection while using a VPN and ik
works ok. But when i test it without the VPN I get a timeout when
trying to login. I have tested this with FileZilla and it works fine.
I've tested it with FTP funtion in TotalCommander and it works, but
slower than FileZilla. Ive tested it with the synapse demo TestFtp and
login fails. What can i do to solve this problem?

Thx.

You can download for free WireShark to find out what is going on.
Without analyzing it is hard to tell.

Hi,

I've installed and used Wireshark but I totaly don't understand what
is happening. I add 2 files, 1 is the test with VPN and the other the
test without VPN. I hope that there is someone who can understand
this.
Thx

I am unable to load your file back in.
When I do look with a simple csv reader at your file, it seems you
have an incorrect Tsl version specified (1.2 you got, but 1.1 wanted)
But of course I can be complete wrong, it is more a guessing.

Sorry that I can not help further!

Thx sofar. I've uploaded a wirshark file of a failed login. Perhaps
this will help.

Sorry, it took awhile. The whireshark data shows the use if TLS2.1 and
that should be TLS1.1. But I don't know where I can or should change
that. Is it in my code, is it in my wifi connection, is it somewhere
at the provider? In case of network issues I'm very ignorant.
Can anyone give me some advice please?

Thx
