some log info issue

Hi Edward,
First of all, thanks for your work on this.
I've had some sls disconnection issues bothering me lately.

2023-08-30 23:48:15:448 SLS ERROR: CSLSSrt::libsrt_neterrno, err=2001, Connection was broken.

I have some questiones for ：

1、CSLSSrt::libsrt_neterrno, err=2001, Connection was broken. //
Is this a global failure or a link failure

2、check_invalid_sock, worker_number=0, player=0x7f0d00a0d400, invalid sock=0, state=2, role_map.size=39 //
this sock=0 it is means ,The peer network is faulty, or is it the SLS side?

3、From the above alarms, can we see whether it is the problem of the sls end or the receiving end?

Looking forward to your reply, thank you very much！
