title: Gekko unreachable server, local solving json file error
body: <p>I think I'm running into the same problem as this stack overflow. </p>
  
  <p><a href="https://stackoverflow.com/questions/57624215/unreachable-server-working-with-gekko-what-is-going-on">Unreachable server working with GEKKO. What is going on?</a></p>
  
  <p>Yesterday I was able to solve my Gekko model and today I'm not even able to solve the examples from the Apmonitor site. Solving takes forever and I get the following error: </p>
  
  <pre><code>ImportError: No solution or server unreachable.
    Show errors with m.solve(disp=True).
    Try local solve with m=GEKKO(remote=False).
  </code></pre>
  
  <p>I tried solving it locally as was suggested in the stack overflow post I mentioned above:</p>
  
  <pre><code>m = GEKKO(remote=False)
  </code></pre>
  
  <p>However, I then got the following error:</p>
  
  <pre><code>Error: 'results.json' not found. Check above for additional error details
  Traceback (most recent call last):
  </code></pre>
  
  <p>and</p>
  
  <pre><code>FileNotFoundError: [Errno 2] No such file or directory: '/var/folders/mr/kgzm2xln40dcc10zkq06drhc0000gn/T/tmpzqxlyw7_gk_model0/options.json'
  </code></pre>
  
  <p>Is the server down and can anyone help me solving it locally?</p>
  
  <p>Edit, code add:</p>
  
  <pre><code>from gekko import GEKKO
  m = GEKKO(remote=False)           # create GEKKO model
  y = m.Var(value=2)    # define new variable, initial value=2
  m.Equation(y**2==1)   # define new equation
  m.options.SOLVER=1    # change solver (1=APOPT,3=IPOPT)
  m.solve(disp=True)
  print('y: ' + str(y.value)) # print variable value
  </code></pre>
