Thank you for the suggestion Alex!
The access.log contains error code / detail "ERR_SECURE_CONNECT_FAIL /
SQUID_ERR_SSL_HANDSHAKE" - which is not too helpful - but the cache.log
contains the more detailed "ERROR: negotiating TLS on FD 19:
Is a TLS fallback prevention mechanism kicking in by error? If so, how
to fix it?
Please let me know if additional log output (the debug log around the
error location did not seem helpful to me though) or a configuration to
reproduce the error are needed.
