Hi guys!
I got TypeError: no implicit conversion from nil to integer on my macbook m1 pro + chrome 114.0.5735.198(arm64).
I added@rbuf_offset = 0 unless @rbuf_offset in .rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/gems/net-protocol-0.2.1/lib/net/protocol.rb:198
And now it works fine for me.
Myabe if will be helpful for some who.

Having the same issue here but in a docker container running Ubuntu 20.04.6 LTS x86_64
Also, same gem version as the author, 0.2.1. The ruby version is different tho, 2.7.7.
