We are getting additional www redirection issue on our dnn websites. Everyday websites redirect and add additional www in url as https://www.www and website can inaccssible.

Exmp:

https://www.domain.com > redirect to https://www.www.domain.com

https://www.domain.com > redirect to https://www.www.domain.com

And save it in browser cache, it auto resolved after few minutes and we need to clear the cache from browsers to access the websites. No dnn / event logs generate on server for that redirection issue.

Can you please help us to investigate and fix this issue?
