There are two main reasons SSL renegotiation commonly fails
- HTTP/2 is in use
- TLSv1.3 is in use
While both of these are valid, Undertow makes it unnecessarily difficult to troubleshoot these are there are no logs, not even TRACE logs to let you know what is happening.
See this mailing list thread where all the details including the specific code in question is discussed:
