After deploy self hosted server in moralis it gives an error
We need more details on which step threw this error. Please share us more details. 
when page loads it shows error in server logs and in console it shows CROS Origin error even though url I made white listed in server
If the website is already whitelisted in CORS and you still seeing cors then there might be a mismatch in the URL. Make sure to match the URL same the website URL. Also, try restarting your server to make sure the code is built and updated again correctly.
