TwitterのAPIを通してツイートデータを取得し、csvに保存している途中でTimeoutErrorがでてしまう問題。１週間前まで問題がなかったのに急にこのエラーが出てきてしまっています。

前提・実現したいこと

TwitterのAPIを通して、ツイートデータを取得し、そのデータをcsvに保存することが目的です。
１週間ほど前まで、問題なくできていたのですが、ここ最近、急にTimeoutエラーが表示され、途中で取得することができなくなってしまいました。

試したこと

最初はネットワーク上のエラーだと思い、インターネットの接続を見ましたが、何も異常がありませんでした。また、URLも確認したのですが、変化はおきませんでした。サーバーに負荷がかからないようにTime関数を用いましたが、だめでした。
そこでAnacondaNavigatorのアップデートを同時並行でやっていたからだと思い、試してみましたが、必ず途中でこのエラーが出てきてしまいます。
もう一度書きますが、先週までツイートデータを問題なく取得できていました。
