Problem in php code

[korud]

Hello, I was using the v1 version of the bingX api but it has stopped working for no apparent reason so I decided to create a complete new code and update it to the v2 version. However, I am getting an error that I cannot solve for more hours than I try to solve it.

When trying to connect to the api and generate some action or query, I get the following error:

placeMarketOrder: {"code":80014,"msg":"timestamp is invalid","data":{}}

In version v2 through php. I only copy, put apikey/secretkey and run. I have usdt.

Another error I'm getting when performing get queries is this or similar:

placeMarketOrder: {"code":80014,"msg":"Null timestamp or timestamp mismatch","data":{}}

How can we solve this?
Could be added to the code?
