I live in China. Recently the download speed has about 5Mbps after 1pm utc time(night in China) with VPN, but the upload speed is fine, about 100Mbps. Without AirVPN, the speed test is normal.
The download speed in the daytime is fine, about 400Mbps.
Any idea how to troubleshooting this?

It's fine now when I am using Merope server. Maybe it's other US server's problem?

And the download speed only affect me when I watch twitch, twitter etc. I can get 30mpbs when I try to download things from google drive or watch youtube. It's really weird.
The speed will be normal after 5:00pm UTC. I try different ISP,  the problem sill exist.
European Server will be faster.
