When cloning the github and running the client on a local host:
The client is very slow in general
The exchange is non functional (just shows as loading continuously).

Tried connecting to different servers.
Is there any way to fix this so that testing can be done locally.

Have a try

After updating the API connection menu showed up. Many thanks!

Chose this one.
I had the same problem today, but this has nothing to do with my clock. Now it's ok, but still far from perfect. New servers are ready to go, but we must wait for official release, which should happen very soon.
BTW new client is 160829.

I recently downloaded the new BitShares 2.0.160813 light software and set up my account. All seamed to be working flawlessly until yesterday when I tried to start the client and got the following screen:

QuoteFailed to sync with the API server
Please verify that your computer clock is correct.
Once you've synchronized your clock, please refresh this page.

I live in the UTC+1 time zone and use Windows 7 x64 with clock automatically synchronized with 'time.windows.com'. I've synced the computer clock and restarted the client multiple times but the problem persists. How do I change API server or otherwise resolve this error?
