We have anecdotal evidence that some SSH servers claim to be able to
perform Diffie-Hellman group exchange, but fail to actually do so
when PuTTY tries to. If your SSH2 sessions spontaneously close
immediately after opening the PuTTY window, it might be worth
enabling the workaround for this bug to see if it helps.
We have no hard evidence that any specific version of specific
server software reliably demonstrates this bug. Therefore, PuTTY
will never \e{assume} a server has this bug; if you want the
workaround, you need to enable it manually.
This is an SSH2-specific bug.
