443 outbound issues

Hi

All of a sudden I am seeing these sorts of issues in my logs:

2018-10-15 15:08:22 ERROR (MainThread) [homeassistant.components.camera.generic] Error getting new camera image: Cannot connect to host maps.googleapis.com:443 ssl:None [Try again]
2018-10-15 15:08:29 ERROR (updater) [telegram.ext.updater] Error while getting Updates: urllib3 HTTPError HTTPSConnectionPool(host='api.telegram.org', port=443): Max retries exceeded with url: /<redacted>/getUpdates (Caused by NewConnectionError('<telegram.vendor.ptb_urllib3.urllib3.connection.VerifiedHTTPSConnection object at 0x714dfc50>: Failed to establish a new connection: [Errno -3] Try again',))

Its almost like all outbound 443 ports are being blocked! I have just reinstalled my PiHole addon but have allowed these URLs as a whitelist. Any idea this is happening? Thanks

I puzzled over error like that with darksky for half of sunday. I rebooted and it worked.
