Getting this error message when using both the desktop app as well as the chrome extension app.
Tried both equipping and not equipping the “What’s My IP?” Item.
Both applications worked perfectly fine until recently.
Please confirm that How to check the basic functionality works fine in your environment. It’s a first thing you should test.
Doesn’t work.Tried all port protocols already.
If you have other desktops, please try to test it again. And are you under network firewalls?
I did a little more testing and it seems that there was another VPN service application that was interfering with Mudfish.
I had previously disabled that program, but it seems like when booting Mudfish (both application and extension) that program would also load leading to the issue.
Everything works fine now, thanks for the help!
Cool! 
I hope now everything goes well with mudfish. Please let me know if there are any other problems.
