Issue Summary

This is reproducible on Data Center: Yes

Confluence appears to freeze in the browser, and does not properly execute allowlist changes when attempting to add a domain entry with a trailing /. This bug persists regardless of https/http, or incoming connection settings.

Steps to Reproduce

Attempt to create a domain allowlist entry with any valid fully qualified domain name (FQDN), beginning with http:// or https://, and ending with a trailing / character.

The allow incoming connections and allow anonymous users options do not affect the outcome. This bug has been replicated in Confluence 7.17.1.

Expected Results

One of the following:

1. If a trailing slash is detected, the slash is removed from the input.
2. The input is rejected, the input field exits the loading state, and a toast is triggered with an error message.
3. The input is accepted.

In Confluence 7.17.1, updating an existing domain entry allows a trailing slash without encountering the issue.

Actual Results

The input field enters the loading state, and never completes. A network request is never sent, and no errors are produced in the client side console.

The attached video shows an example of the behaviour, I am refreshing the page manually to clear the loading state.

Workaround

Remove trailing / characters prior to creating a domain allowlist entries.
