I'm having same kind of issue when accessing coinmarketcap API. It does not happen regularly but doesn't feel the frequency of happening it is good. Time to time I get this error.

HTTPSConnectionPool(host='pro-api.coinmarketcap.com', port=443): Max retries exceeded with url: /v1/cryptocurrency/listings/latest?start=1&limit=200 (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x7fe54487dbb0>: Failed to resolve 'pro-api.coinmarketcap.com' ([Errno -2] Name or service not known)"))

Used Python version 3.9 for it to run on a docker container. But used Python 3.12 for development.

Need to try using different python version. Feels that there is something going with Python requests library.
