Is it the same computer from which you were usually connecting?

Perhaps you are inside an institution which has a firewall or a router that blocks a connection to a custom TCP/IP port? If so, you need to contact the IT to allow the connection to your server's port. The port is visible under the "Host" field in the connection window (when you expand it using the "+" button).

Can you please check if you can reach the server's port using this tool:

http://ping.eu/port-chk/

Type the server's IP address and port there and click on "Go". Does the port appear "Closed" or "Open" to your computer?

OK, this means that the port and IP you have are correct. Let's test if the computer can connect to that port and IP. Please do the following:

1. Install Telnet client:

Click Start > Control Panel.
Click Programs and Features.
Click Turn Windows features on or off.
In the Windows Features dialog box, check the Telnet Client check box.
Click OK. The system installs the appropriate files. This will take a few seconds to a minute.

2. Run "Cmd" (command line) and type:

telnet [ip] [port]

If the port is open, you will see a blank screen. This means that the connection is successful. If the port is closed, you will receive a Connect failed message.

What is the Telnet's output?

Would it be an issue with the version? 7.5.4

The thing is that except for the telnet, we don't see any incoming connections arriving at the server. Can you please check if the Windows Firewall is blocking the connection, or perhaps some other anti virus application?

In Control Panel, select Windows Firewall and click on "Allow an app or feature through Windows Firewall". Do you see "Lantiv Scheduling Studio" in the list? Are the "Private" and "Public" check boxes selected?

Hi.

I'm having the same issue noted in the thread. I did all the steps noted, with "open"/functioning status. I didn't check the last step--my employer uses the Symantec Endpoint Protection client. I checked the network traffic in Symantec, and Lantime seemed to be allowed through.

Thoughts?

Thanks.

We can see the connection attempts from your side to the server, but looks like the server responses are being blocked from reaching your computer because it keeps on trying to reconnect even though the server receives the correct username and password and responds with a successful login. The next step would be the client-side asking for the list of files on the server, but that request never comes in. If we try to connect to the server from our computer for example, we can successfully connect.

This leads us to believe that there is a firewall setting either on the computer or in the institutionís router which prevents the data from the server from reaching your computer. The solution would be to add the serverís IP address and port to the firewallís allowed incoming connections or to the routerís whitelist. Perhaps the IT department of the institution also know how to do this on the institutionís router. You can also try to connect from a home computer and if this works, it would also mean that the institution is behind a firewall which blocks the communication with the server.
