Can't access gui

[dockzero]

I have a new Dell PC (Windows 10) and I have tried Firefox, IE, and Chrome to access the GUI of a gateway device or a server. I had the same issue on my old pc running Windows 7. The only way I can access it is to restart my pc then I can log in. After awhile it starts again and I have to restart my pc once again. Any ideas? Thanks

Be more helpful please, any message, what exactly happens, when it's not able to get to the device?

This is what Firefox gives me:

The connection has timed out

The server at 10.XX.XX.XX is taking too long to respond.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

After I reboot then I can access. Then after a few hours it stops again.

I think I finally found my problem. I have a vpn network that I log into at times and after doing a tracert I found that I was trying to use that network which is blocked instead of my main network. Don't know why I didn't think of this before. Live and learn. Thanks
