Comment 23 for bug 1971538

I have the same issue as Samuel.
I can connect to the hotspot just fine, but the connected devices don't have access to internet.

Strangely enough I did find one workaround that fixes the problem for me in this answer:

The -999 priority doesn't seem to matter, but if I set the hotspot to start automatically and then reboot, connected devices can access the internet. Also, if the hotspot is started automatically I can stop and re-start it and things still work.
