Cannot play game on browser as connections to api.chess.com always failed

starts from a few days ago (maybe May 9th) I cannot play online game on browser. The chess board with pieces is rendered but inoperable and steps window not rendered. With network sniffer I found the connection to api.chess.com is always failed with "uncompleted" status. Changing the game's connection setting didn't help. It is weird because I can connect the api directly in separated browser session. Other JavaScript connection to www.chess.com is also okay.

Any idea or suggest is appreciated!

location: China

OS/browser: iOS/Mac OS. Safari(in iOS/mac)/Microsoft Edge(Mac)

This really isn't relevant to this club, but are you using a VPN or other proxy? It's possible that's causing issues.

You might also try clearing your browser cache.

Thanks Martin. Asked here because i was thinking the issue may caused in the api end so maybe (just maybe) the developers here have more experiences.

Testing this problem now with various networks and found it could related with my local network provider.

Before the issue fixed in the provider end do you / anyone know if there is more traditional way (no live pulling nor web sockets but just form POST/GET) can be used in browser end for game play? I guess no but just a hope...

Maybe worth asking in one of the chess.com Chinese clubs if anybody has that same local network provider?

Thanks for the nice suggestion. Will check the clubs. Thank again for all reply!
