I have a business partner in China. I need connect to their server (in China) from time to time. In recent several months something I don't understand happened. I cannot connect to the server if I use computers with internet cable, but the server is accessible if I use cell phone's data. Here are more details:
1) It is not accessible by computers with internet cable. I have tried different local internet providers (att and twc).
2) It is accessible by cell phone, as long as data is used. It seems it does not matter which carrier the data plan is from. I have tried att, t-mobile, and verizon. All works. I also tried their hotspot devices. They work as well.
3) It is not accessible by cell phone using wifi from router.
4) It is accessible by computers if they are connected to cell phones (cell phone as hotspot, using data).
So it is quite clear. It does not matter what devices used, but does matter which way internet is connected: it is not accessible by using cable internet (and their wifi), but accessible by data plan.
Any idea why? and any solution to connect it by computers with cable internet?
btw, here is the server address, so you can test easily:
Thank you very much!
