Wrong Redirection

I have a domain running a wordpress webpage and something goes wrong with the redirection… I am not sure what is going on.

https://www.smartercleaners.co.uk/ – this doesn’t work but surprisingly without www it works https://smartercleaners.co.uk/.

It was working before and this error happened recently. I did install the new version of wordpress and all of the new plug-ins.

Thanks in advance
