I bought a domain and hosted a site with Wix. Recently, I needed a custom site for which I bought a hosting from Namecheap and uploaded the site files to namecheap server. But Wix wont allow me to edit the nameservers of the domain i have from them. So I added the A record and modified the CNAME record as shown in the image below. It's been 2 hours. but the domain still says bad gateway when visited. How do I solve this?
