I sent to the server “https://fapi.binance.com” endpoints: “/fapi/v2/account” or “/fapi/v2/balance” with parameters like: “recvWindow=10000&&timestamp=1632537880895&signature=signature_hashstring_here” but receive server json respond like this: {“timestamp”:1632537611108,“path”:"/fapi/v2/balance",“msg”:“System error”}
Could you say what a problem?
I configured API key as shown on the screenshot:

Hi.
Probably the servers were over-occupied at that moment, please try it again, thanks.

I received message: “System error” from server because there was a mistake in parameters: double && instead of one &.

I fixed my mistake but binance server does not respond now.

I resolved my problem with this endpoints.
I send request this way:
curl -H “X-MBX-APIKEY: apikeygoeshere” -X GET https://fapi.binance.com/fapi/ v2/account -d timestamp=1578926101 &signature=bbce62e6f607e444063f46ad83b0f4e5859980df717dd8ac436357e1783aa828

but correct request should be:
curl -H “X-MBX-APIKEY: apikeygoeshere” -X GET https://fapi.binance.com/fapi/ v2/account?timestamp=1578926101 &signature=bbce62e6f607e444063f46ad83b0f4e5859980df717dd8ac436357e1783aa828
