Homepage App Icon Redirect Issue After Custom Domain Setup

I set up an n8n application and configured it to use my custom domain for access. While the n8n app works when accessed directly via the custom domain, clicking its icon on the clawcloud homepage still redirects to the old (non-functional) domain, and fails to load. I tried updating the WEBHOOK_URL environment variable from the old domain to the custom one, but the homepage redirect persists. How can I resolve this?
