Error "For input string:"268:fd07:4::1" when accessing Egit remote

We are developing a web system using Eclipse.

Using the Egit plug-in, place the source code on the git server for configuration management.

I have two computers.

1st: Machine: iMac 27" (latest)
OS:Mac OSX Yosemite 10.10.2
2nd: Machine: MacBook Pro 14" (latest)
OS:Mac OSX Yosemite 10.10.2

Egit can be used on the first machine without any problems, but
On the second machine, when I push or pull remotely, the following error occurs and I cannot operate it.The second one can push and pull if you use a command from a terminal.

Error Contents

An internal error occurred during: "Pulling Branch master-project name".
For input string: "268:fd07:4::1"

• Operating with the first machine without any problems
• Second command operation works well

Therefore, I think it's a problem with the environment of the second Eclipse, but I can't find a solution.

The difference between the first one and the second one is that the first one is in the company and is connected through the company's network.
The second is at home and connected via a home network.

I'm sorry, but I appreciate your cooperation.
