500 is a generic server error.

Can you please wrap the logs in ``` symbols or paste it somewhere like hastebin. It's impossible to read this way.

Supprisingly this is 1 line of the log file from the wings.log file, becuase everything was working seamlessly until i did the update the other day, and i cant restart servers as they fail.

You either uninstalled iptables or did something to modify them enough that docker is throwing a fit. Stop the daemon, restart docker, and then start the daemon again and it should be fine.
