OpenSSL refused to accept a TLS client connection with a generic
SSL_ERROR_SSL:
A non-recoverable, fatal error in the SSL library occurred, usually
a protocol error. The OpenSSL error queue contains more information
on the error.
AFAICT, Squid does not have the code to examine OpenSSL error queue
beyond the surface level (shown in your cache.log), but that does not
mean there is actually more information in that queue in your particular
case. Said that, quality pull requests (or sponsorship for) adding deep
error queue inspection support are welcomed.
I trust there are no other potentially relevant ERRORs and WARNINGs in
your cache.log.
It sounds like you can trivially reproduce the problem. If so, a capable
developer with access to your box should be able to triage it further.

It is most likely related to the SSL handshake. FWIW, I would worry
about it because it should not be happening under normal conditions.
HTH,
