Steps to reproduce
Launch the docker container with beer sample and exposed ports as per documentation. Try to open connection via gdotv. (Also attempted to connect via java app to arcadedata/arcadedb:23.6.1 seeing the same error.)
"Failure to initialize channel" is repeated multiple times, it seems to be a resulting error from the first connection failure.
Could not identify the source of the NoSuchMethodError, the constructor should be available in Netty 4.1 and this seems to be the version used by arcade as well:
https://netty.io/4.1/api/io/netty/handler/codec/DefaultHeadersImpl.html#DefaultHeadersImpl-io.netty.util.HashingStrategy-io.netty.handler.codec.ValueConverter-io.netty.handler.codec.DefaultHeaders.NameValidator-int-io.netty.handler.codec.DefaultHeaders.ValueValidator-
(Some other versions only offer the constructor with fewer parameters.)
