JMP authorization - Connection errors

[#1]

Until this week everything was working fine with my JMP 18 but this week the My JMP Authorization window reports a connection issue. 

My IT team have checked my computer, reinstalled JMP 18 but the issue is still the same.

As a test I installed JMP 16 and that works fine.

The issue appears to be connecting to the JMP server for authentication.

Has anyone else had this issue, what was the solution?

Thanks
