  1. oldjamey's post in Keycroc cannot connect to c2 was marked as the answer   
    This is the only thing that worked for me. It took me hours of troubleshooting to finally find my way to this post.  The only thing that I might add is that this should also be done on the c2 server and not just the croc.  It was only when I updated both that it successfully connected.  Thanks for the help.  @Darren Kitchen, they should really address this in the documentation or fix this via the device firmware and c2 binaries.
    Until then, just create use this patch script from @dark_pyrro's commands above and save in `~/c2_connection_patch.sh` on the croc and c2 server, then run `sh ~/c2_connection_patch.sh`:
    #!/bin/sh # check if patch needs to be applied: if grep X3 /etc/ca-certificates.conf | grep -qE '^!'; then echo 'system is already patched.' exit 0 fi # backup /etc/ca-certificates.conf: echo 'backing up /etc/certificates.conf...' cp /etc/ca-certificates.conf /etc/ca-certificates.conf.bak # blacklist the X3 root certificate: echo 'blacklisting the X3 root certificate...' sed -i '/^mozilla\/DST_Root_CA_X3/s/^/!/' /etc/ca-certificates.conf # update ca certs: echo 'updating ca certs...' update-ca-certificates -f echo 'done.' echo echo 'please reboot hak5 device, and restart cloud c2 server.'
