------------------------------------
Tried with C* 3.11.11, and it works...

Release version is: 3.11.11 {code}
I'm testing with the v2.3.4 release of zdm-proxy.
However, if you can reproduce it, it's probably an issue with my setup...

> If the server's ProtocolError response comes with stream id 0 then [this
> code|https://github.com/apache/cassandra-gocql-driver/blob/0326fae3617dd19b901f2e9a97479c04fc11e05a/conn.go#L685-L700]
> will create the protocol error object.
> If the response comes with a positive stream id then [this
> code|https://github.com/apache/cassandra-gocql-driver/blob/0326fae3617dd19b901f2e9a97479c04fc11e05a/conn.go#L1314-L1330]
> will create the protocol error object. This latter way of creating the error
> makes [the regex check not
> work|https://github.com/apache/cassandra-gocql-driver/blob/0326fae3617dd19b901f2e9a97479c04fc11e05a/control.go#L210-L245].
> This was found when trying to connect to
> [ZDM-Proxy|https://github.com/datastax/zdm-proxy/] but connecting to a C*
> 3.11.x cluster works fine.
