If IE can't open either, it may be a network problem.
2. If IE can be opened, try to switch the browsing mode to compatible in sogou address bar. In sogou-Tools-Sogou High Speed Browser Options-Network Connection-Use sogou Accelerator, or use custom and use IE proxy.
3. Install the latest sogou 3.2, and click Browser Help-Browser Repair Tool-Manual Repair-Clear Temporary Files, reset the acceleration strategy, and restore the browser settings.
I just tested that sogou can open it. If you have any questions, go to Sogou browser to post feedback.
