Journal transfer from one domain to another domain OJS 3.3.0.10

I tried moving domains from the same server and hosting but there was an “error 400 bad request”

in the config.inc.php file I have changed the base_url to the new domain, and I have changed the allowed_hosts to the new domain
please if anyone can help, thank you!

Just remove the https:// in the allowed_hosts part. And use single quotes outside the square brackets, as in the example given.
