Typically each socket address (protocol/network address/port) is only allowed to be used once. (127.0.0.1:9127)

[Liu Jianjie]

Hello, please allow me to introduce my problem. I hope someone can see it.

• Problem Description

  My requirement is for OpenAI to help translate Chinese into the corresponding language. Since there are multiple Chinese languages, each to be translated is a Task. I use List to add all Tasks, but I have SemaphoreSlim to control the number of concurrencies at a time. , I currently set it to 50. But after the network request, it was informed that Typically each socket address (protocol/network address/port) is only allowed to be used once. (127.0.0.1:9127)

      {
          var languageStr = LanguageHelp.GetLangugeStrByEnum(diffExcel.languageType);

          {
              tasks.Add(TranslateTextAsyncWithCell(cellCls, languageStr, semaphore));
