It is not a file on your computers disk. It is a connection attempt
from one of your phones. If a phone is configured to use tcp without
tls and connect to the port used for tls (default 5061) you will see
a message like this. (just an example - different situation here)

"WARNING[1170]: tcptls.c:673 handle_tcptls_connection ..."

Handle ... connection ...

"Problem setting up ssl connection: error:00000000:lib(0):func(0):reason(0)"

ERR_get_error returns 0 if there is no error in the queue. According
to the description [1] this may happen and it would be possible to
find out more about the error.

Try to connect using "openssl s_client".
