Updates No Longer Seem to Show

My Hassio RPi installation doesn’t show updates anymore… I’m stuck on 104.3. Found this error message:
20-03-17 14:11:54 WARNING (MainThread) [hassio.updater] Can't fetch versions from https://version.home-assistant.io/stable.json: Cannot connect to host version.home-assistant.io:443 ssl:None [Try again]

Anybody else seen this problem? Ideas?

Do you have a firewall? Try to access the url from your laptop or pc.


Yup,url works from the web browser! But still no update info in HA.
