I recommend finding the place in the debugging cache.log where Squid
generates the above error response and then going backwards to find the
cause.
OK Alex, got it.
In the meantime, I searched for the events around the time this happened.
BTW as a side question I'd like to know if I can change the timestamp in cache.log so it can print the unixtime as in access.log.
In any case, here's the relevant part:

The first 4 bytes were ones which cannot exist at the start if any HTTP
message - so the protocol being bumped on port 443 was not HTTPS.
Squid then proceeds to generate and send the invalid-request error
response to this non-HTTPS over port 443.
