Cloudflare zero trust application white page


I published a HTTP site (source is localIP:8080) via Cloudflare zero trust.
But when i view the local IP the site fully works. But when i go to the published some elements are white.
Any toughts ?

Local application

Your browser’s Dev Tools (F12 in Chrome) should clarify what the issue is.

You’re calling an ws over HTTPS, it should be wss on HTTPS as already stated.

Before moving to Cloudflare, was your Website working over HTTPS connection?

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

  1. Make sure there is a valid SSL certificate (Let’s Encrypt on the origin)
  2. Make sure the SSL/TLS option is set to “Full Strict SSL”
  3. Make sure WebSockets feature is enabled at Cloudflare dashboard
  4. Use WSS scheme

Make sure the port is for the HTTPS one from the link below which is supported and compatible with the Cloudflare proxy mode :orange: :
