I used the domain in Shopify previously. I deleted it in the Shopify panel. The server is working well when pointing to any other domains and it works well when skipping the Cloudflare proxy and installing free SSL.
I read from previous topics that mention the domain was still connected to Shopify’s Cloudflare Saas account so I need to create a ticket on Cloudflare but am not able because I use the pro plan. I hope somebody helps me
As you suspected, this is likely due to the domain being stuck in Shopify’s system from a previous configuration.
Generally the quickest way to resolve this is with Shopify directly - please try contacting them and ask them to remove all Cloudflare configurations for your domain, specifically SSL for SaaS / Custom Hostnames.
If that’s not successful, you can reach out to Cloudflare via [email protected] and they can handle this for you manually - be sure you mention you used to use Shopify and need to remove the previous custom hostname / SSL for SaaS config. Feel free to reply with a support ticket number if you do this, and it can be escalated here
Please ask them specifically to remove their SSL for SaaS / Custom Hostname configuration for your domain from their Cloudflare setup. They will likely have to escalate the issue from frontline support but it is easy for them to resolve.
Is is a very frustrating situation to be in and Cloudflare are supposedly working on better solutions but for now it requires the provider to removed their custom hostname configuration. For some reason, some providers make this way harder than it needs to be and Cloudflare have to manually remove it.
