MultiperformTenSessionsGetTest Test Case Fails on macOS Nondeterministic

[COM8]

Description

On macOS systems the MultiperformTenSessionsGetTest test case fails nondeterministic.
In case it fails, it gets an error indicating that the connection establishment failed inside curl.

This issue still exists, even in case we update to curl 7.85.0.

Example/How to Reproduce

Execute the MultiperformTenSessionsGetTest test case on macOS.
For this one first has to enable it again in the source code since I disabled it in #863 for macOS for now.

TEST(MultiperformGetTests, MultiperformTenSessionsGetTest) {
    const size_t sessionCount = 10;

    MultiPerform multiperform;
    Url url{server->GetBaseUrl() + "/hello.html"};
    for (size_t i = 0; i < sessionCount; ++i) {
        std::shared_ptr<Session> session = std::make_shared<Session>();
        session->SetUrl(url);
        multiperform.AddSession(session);
    }

    std::vector<Response> responses = multiperform.Get();

    EXPECT_EQ(responses.size(), sessionCount);
    for (Response& response : responses) {
        EXPECT_EQ(std::string{"Hello world!"}, response.text);
        EXPECT_EQ(url, response.url);
        EXPECT_EQ(std::string{"text/html"}, response.header["content-type"]);
        EXPECT_EQ(200, response.status_code);
        EXPECT_EQ(ErrorCode::OK, response.error.code);
    }
}

Possible Fix
