"openssl(1.0.2k) s_client -connect data.reversinglabs.com:443 -tls1_2" gives error: SSL3_GET_RECORD"wrong version number:s3_pkt.c:365

[Geek Geek <bcjunk123@xxxxxxxxx>]

I run into the following issue when I use openssl 1.0.2k  (amazon linux2) to check the connection.

[ec2-user@ip-172-31-29-28 ~]$ openssl s_client -connect data.reversinglabs.com:443 -tls1_2

[ec2-user@ip-172-31-29-28 ~]$ openssl version
OpenSSL 1.0.2k-fips  26 Jan 2017

If I use brew install the latest openssl  (3.0.*), then the same command works.   As our production is still using openssl 1.0.2k, my question is what causes this error and whether this is really an issue.

Thanks.
