Error calling List OrderBook: The SSL connection could not be established, see inner exception.

[forReason]

From time to time I receive this error Message:

The SSL connection could not be established, see inner exception.
Error calling List OrderBook: The SSL connection could not be established, see inner exception.

Line causing the error:

OrderBook requestResult = API._spotApi.ListOrderBook(currencyPair.UnderscoredString, orderDepthAggreation, depthLimit, returnOrderbookId);

whats causing the error or how to mitigate it?

Seems the connection to the server is not stable. Do you encounter such errors while calling other methods? Where is your client located?

[forReason]

Haven't gotten this error on another method yet. Latency/response time seems quite high with > 1s on average. okx response times are around ~20ms for an orderbook.

Client is located in switzerland on 10gb network connection Edit: also encountered simmilar issue, when trying to open a websocket connection:

Uri host = new Uri("wss://ws.gateio.io/v4/");
Socket = new ClientWebSocket();
Socket.Options.KeepAliveInterval = TimeSpan.FromSeconds(5);
Socket.ConnectAsync(host, CancellationToken.None).Wait();

error:

AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: NotTimeValid

edit2: after a good amount of time digging around with the websocket api issue, I found the Certificate is indeed invalid (out of date)

Could it be that the API is load balanced and only occasionaly host 2 will provide an answer (with an invalid certificate)?

issue seems to be resolved now,

Coming back to this. As of today, I am unable to open a connection from any of my computers at home.

From my laptop at work, It worked. Different windows 10 cersions are involved. I did a wireshark. The server bumps me, does not accept the client hello: gateshark.zip

I wonder if thats some kind of ban behaviour? Although Gate works totally fine in the webbrowser
