kex protocol error: type 30 seq 1
After upgrading openssh to 6.9p1-2 we were unable to connect to the server using putty.
In PuTTY, go to “Connection ? SSH ? Kex”. There, select “Diffie-Hellman group exchange” and move it to the bottom of the list, so it is not used. The connection should start working as normal again.
- An error has occurred, which probably means the feed is down. Try again later.
