Hi, testing has revealed that when TiCDC connects to an authenticated Kafka, if the password contains special characters such as $ or @, it cannot connect even when using the \ escape character. This issue has occurred in both versions 6.5 and 5.4 (with different error messages). Changing the password (to one without special characters) allows the connection. Users inevitably use special characters when setting passwords, so we hope for compatibility.

Thank you for the feedback. Currently, this issue requires using URL encode to escape special characters. We will consider how to optimize this issue in the future.

Encountered the same issue with DM, let’s optimize it together later.
