On a previous passage I connected up my Iridium GO to my Surface pro tablet without any problems. Now, I can connect to it with my mobile phone but cannot get on to the Surface Pro. It shows me a message that my device is connected but may not be able to reach the internet. When I press the the troubleshoot button, the tablet tells me that “your DNS server might be unavailable. “Following a suggestion I have uninstalled a McAfee antivirus app even though I haven’t paid a subscription for years. Any help gratefully received. Martin
