StrongVPN has been working consistently in China since October 2017 and has been named one of the best VPNs for China by Comparitech. StrongVPN is currently working diligently to find a resolution with certain servers not working in China. For those users in China, we do recommend coming to our Live Chat during non-peak hours which would be considered 5pm 12am local time. Further, we have noticed both our New York and Miami server locations are still very accessible from China. We ask that customers try those server locations before coming to the Support Page.”]
