I got this too, running the latest version from a windows host to a Ubuntu SSH server.

Hello! Please help with solving this problem, I also get the same error when connecting via SSH Ubuntu https://disk.yandex.ru/i/IM3a1Ga8_xGxYw

ghost commented 1 year ago

The problem was related to the size of the greeting specified in .bashcr I added to the standard greeting there

#welcom!
if [ -x /usr/games/cowsay -a -x /usr/games/fortune ]; then
    fortune | cowsay -f tux
fi

this increased the packet size on the first connection!

#fortune | cowsay -f tux

solved the problem!
