Below is strace output for cyrus-master during manual sync_client invocation:

I interrupted the output a little while after I'd seen these lines in
the logs of the A switched to replica:
Jul 11 18:45:18 imapsite-master syncserver[29913]: SSL_accept()
incomplete -> wait
Jul 11 18:45:40 imapsite-master syncserver[29813]: SSL_accept() timed
out -> fail
Jul 11 18:45:40 imapsite-master syncserver[29813]: STARTTLS failed:
imapsite-replica [10.10.0.188]
Hope this helps somehow!
