Fix Cloudflare 526 Subdomain

Job ID: 40111349

Budget: $30 – $250 USD

I’m running my sites on a VPS with CyberPanel in front of LiteSpeed and I route everything through Cloudflare. The main domain is locked down with Cloudflare’s SSL and operates perfectly in Full (Strict) mode, but every sub-domain I spin up throws the dreaded “Invalid SSL certificate – Error 526.”

I need someone who knows CyberPanel’s SSL manager, Cloudflare Origin certificates, and the quirks of Full (Strict) to walk me through the right sequence:

• generate or import the correct certificate for the sub-domain,
• install it in CyberPanel (or replace it with a Cloudflare origin cert if that’s cleaner),
• confirm the chain is trusted so Cloudflare stops flagging it, and
• document the steps so I can repeat the process myself later.

You’ll get root SSH and CyberPanel access plus the Cloudflare dashboard; we can screen-share or trade commands—whatever moves faster. We’re finished when the sub-domain loads over HTTPS with no certificate errors, HSTS still passes, and the change survives a reboot.
