AWS S3 Bucket name already exists

I know this question has been asked before, but replies didn't really help my case. I am trying to create a bucket in S3 and I always receive the 'Bucket name already exists' error. I tried any possible combination but no luck, also the format is compliant to the docs.

Any idea of what I am doing wrong?

Thanks

So, I finally solved my issue.

As I stated in the description of my question, my problem was not the formatting or the validity of the bucket name, the name was also unique and not used. Weirdly enough, I could not create the bucket when signed in using Chrome, but I succeeded doing it using Edge.
