Well whatever, it's bloody annoying.
Why all of a sudden??
Hard to say, I guess it thinks you are a bot not a human (but it usually just throws up a check box), where it knows I'm 'Certainly Bot'
Has your ISP changed it IPs or method of connection ?
No nothing changed. Is the issue forum related or Browser, any idea?
Well yes and no.
Yes, Forum - When I have to log in, I can see the fact that ReCaptcha is enabled on that page.

https://forum.avast.com/index.php?topic=234675.msg1549226#msg1549226 No, Browser - I think that if it were directly browser related - I would have expected to see a much larger activity level about the problem.
I don't know if it might possibly be add-on related, HideMyAss style add-ons where it is trying to mask you. I use uBlock Origin but have it disabled for the Forums. I also use uMatrix and google analytics I haven't allowed. I also use Privacy Badger and Disconnect add-ons and both are enabled on the forums.
You could try running your browser with add-ons disabled and see if that makes any difference.
