try & except が発動しない

Question

PythonでAPIでhttp通信しようとすると１５００回に一度程度に「RemoteDisconnected」と通信エラーが出て止まってしまいます。
try & except を使ってエラーが出たときに接続再試行すればよいのですが、try & except に引っ掛かってくれません。
except RemoteDisconnected : でも
except http.client.RemoteDisconnected : でも
except http.client.RemoteDisconnected as e:　でもダメでした。

exceptのあとに続くものを教えていただきたいです。
ご教授よろしくお願い致します。

import http
from http.client import RemoteDisconnected

try:
   kline = ccxtBybit.public_get_kline_list({"symbol":"BTCUSD","interval":"1", "from":int(time.time())-120})
except http.client.RemoteDisconnected as e:
        print("connect error!!")
        continue

The above exception was the direct cause of the following exception:

Answer 1

上のエラーのために下のエラーが起きたと言っているので、

一番下のエラー、つまり

ccxt.base.errors.NetworkError

でしょう。

指定する方法がわからなければ、

except：

というので捕まえるのも可能です。

指定する方法を調べていたら、以下が見つかりました。

python3 明記したエラー文がキャッチされない

ありがとうございます。
お陰様でエラーを対処することができるようになりました！
過去にも同じ質問があったのですね、自分の調べ不足でした。
