So I had a strange issue crop up over the last week. I have 2 computers and an iPhone that I have Teamviewer installed on. Everything has been working perfectly for quite a while now but suddenly last week the computers lost the ability to connect to each other. Now I just get Protocol Negotiation Failed. Please try again.
I tried rebooting and even looking at the settings to make sure nothing obvious had changed but still couldn't connect to either PC from the other one. My next step was to reinstall teamviewer and I did that on both PCs. Even after that they still can't connect.
The really odd thing is that my phone can connect to both PCs with no problems and both PCs show as online in teamviewer. The phone is also not using wireless so it isnt on the same local network as either PC when I am connecting with it.
I tried searching but couldn't find anything like what I am experiencing.
