Can't reach nabucasa, telegram and other services from home assistant

Hi, I am using Hass.io.
It’s seem that I can’t reach nabucasa, telegram and other services from home assistant.
I keep getting those errors:

Error while bootstrap del webhook: urllib3 HTTPError HTTPSConnectionPool(host='api.telegram.org', port=443): Max retries exceeded with url: /bot584708815:AAEM13nLb1DCCDyKiNZPq_xyPBBA6QrccXo/deleteWebhook (Caused by NewConnectionError('<telegram.vendor.ptb_urllib3.urllib3.connection.VerifiedHTTPSConnection object at 0x699e9070>: Failed to establish a new connection: [Errno -3] Try again'))

Unable to connect: Cannot connect to host cloud.nabucasa.com:443 ssl:None [Try again]

Can someone help ?

I have exactly the same errors suddenly, quite some components stopped working, like the Tado and Scrape components, everything trying to make an SSL connection to the internet. I’m running it on an RPI4 & updated to the latest version.

Whaaat, now it works again?? Maybe it was the Pi-Hole component messing things up. I will investigate.

Thanks but I don’t use Pi-Hole.
Any other suggestions ?
