If you are experiencing trouble connecting to a service that requires Cloudflare WARP (e.g. Remote Desktop or Linux), the issue will likely be resolved by re-authenticating your Cloudflare session.
Method 1: Respond to pop-up to re-authenticate
When you turn Cloudflare on and attempt to connect, you may see this pop-up message prompting you to re-authenticate. If so, click the Open Browser and Re-Authenticate button.
Method 2: Manually re-authenticate
If you don't see the pop-up from Method 1 above, you will need to manually re-authenticate by opening Cloudflare Preferences. To do this, click the Cloudflare icon > Settings (gear) > Preferences > Account tab. From here, click the Re-Authenticate Session button.
Confirmation that re-authentication was successful
Regardless of which method you used in the above steps, you should see the confirmation page shown below to indicate Cloudflare WARP was successfully re-authenticated. At this point, you'll want to close any Remote Desktop Connection windows which had been opened before re-authenticating, and then attempt the connection again.
