background
I bought a server in Los Angeles, and every time I pinged, there was about 85% packet loss, which was very painful and I couldn't do anything.
I thought it was blocked by the wall, so I asked the official to change the IP for 3 dollars, but the result is still the same
solution
I opened a hotspot with my Telecom mobile phone, and everything went fine.
in conclusion
The mobile network sucks! ! ! ! It took me several days and 3 knives to make me happy, and my heart hurts! ! ! Do not use the mobile network to engage in it! !
