I just got the latest version of JRemote and its the first time using it. I'm using it on an iPhone 6Plus and the OS is current on the iPhone (9.3.5). On my laptop I'm running MC20, and the OS is 10.7.5. I have firewalls turned off in my preferences. I have not been able to connect, but instead keep coming up over and over again with an "Invalid Access Key" message. I have double checked my keyboard preferences and turned off all options there - using a standard Qwerty keyboard with all options toggled OFF. The server response is that the "Keyid XXXXXXX not found". I have re-entered it numerous times and checked and triple checked that upper and lower case and numerals are correct. MC20 is up and running, and that is were I'm obtaining the access key. I also tried connecting via IP address, using the JRiver IP Check tool to obtain my current IP address. When I do this I get repeated connection timed out messages, again, triple checking the address is entered correctly. I have tried with and without authentication turned on, and still no connection. Again, no firewall blocking port 52199 - though I have no idea how to actually assure that MP has access to port 52199 specifically via the general system preferences, but nothing is on that would be otherwise blocking it as far as I know. What am I missing??
