SSL flexible is causing too may redirects error

hello!
I had the 522 cludflare error.
i talked to bluehost and they told me to change the SSL to flexible and not full and that this problem won’t appear no more. but after I changed it i couldn’t edit my blog as i hade “too many redirects” error.
I changed it again to SSL full and it is solved, but then i’ll probably have the 522 error again.
what should I do?

524 Error*

bluehost told me cloudflare needs to update my A record
