Stop displaying this error and print instead just "error"

how to stop displaying this error and print instead just "error":
HTTPConnectionPool(host='domain.com', port=80): Max retries exceeded with url: /api

Problem using Python client library for Plaid

I'm following the tutorial, but I get an error when I use item_public_token_exchange.
itempublic_tokenexchange
exchange_request = ItemPublicTokenExchangeRequest(
public_token=plaid_token
)
exchange_response = CLIENT.item_public_token_exchange(exchange_request)
the error:
urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='sandbox', port=80): Max retries exceeded with url: /item/public_token/exchange (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x10f1493a0>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known'))
Not sure what is happening.

It looks like the problem is that you are trying to connect to sandbox instead of sandbox.plaid.com. Make sure you have your host set up as plaid.Environment.Sandbox (or, alternatively, sandbox.plaid.com) and not just sandbox.

How to catch exception MaxRetryError?

I have a list of proxy addresses for which I want to connect the telegrams-bot.
Proxies can be blocked over time or simply not work, this can be seen by the MaxRetryError error.
But I can't catch an error. I have an error in logs.
I want to catch an error and switch to another proxy server.
from telegram.ext import Updater
REQUEST_KWARGS = {
'proxy_url': proxy_url,
'urllib3_proxy_kwargs': {
'retries': 0
}
}
updater = Updater(token=TELEGRAM_TOKEN, request_kwargs=REQUEST_KWARGS)
queue = updater.start_polling(bootstrap_retries=0)
.....
raise MaxRetryError(_pool, url, error or ResponseError(cause))
telegram.vendor.ptb_urllib3.urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='api.telegram.org', port=443): Max retries exceeded with url: /bot877422445:AAEGBD0D9stJKMF6PvCClChx8MNMGX-vLEY/deleteWebhook (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<telegram.vendor.ptb_urllib3.urllib3.connection.VerifiedHTTPSConnection object at 0x11572df98>: Failed to establish a new connection: [Errno 61] Connection refused')))
......

This way ?
try:
updater = Updater(token=TELEGRAM_TOKEN, request_kwargs=REQUEST_KWARGS)
queue = updater.start_polling(bootstrap_retries=0)
except MaxRetryError:
#doSomething
