HACS stopped working after updating to 2021.4.3

Hello

I just updated my hassos to 2021.4.3 and HACS (that was running just fine before) stopped working.
The log says:
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ReadTimeoutError(“HTTPSConnectionPool(host=‘pypi.org’, port=443): Read timed out. (read timeout=15)”)’: /simple/hacs-frontend/

It seems like it cannot access pypi to download the necessary python libs.

Has anyone experience such behavior ? Is there a known solution ?

Thank you

I am also seeing similar connect issues with docker core after update to 2021.4
