This has been extremely frustrating. Everything on ID has been working great for a long time.
I downloaded some VPN software from pureVPN. I did not even mean to install it on my main computer running ID. It was for another computer but I installed it on here on accident. After installation ID lost connection to the slaves it was connected to.
After verifying addresses all matched, the problem still remained. I uninstalled pureVPN software, uninstall/reinstalled ID, restarted my computers but the problem still remains.
I can verify that ID does detect the computers because I am able to move the mouse over to the slave computer for a few secs then it will say "slave ... didnt respond".
Here you can see the correct address:
Here it says the slave didn't respond:
Here you can see the mouse (watermark effect) on the other screen for a second:
Here the slave is in master mode while the master tries to connect:
I don't know what network settings got messed up but I am about to reinstall my entire OS, this shit is starting to piss me off.
