Yesterday discourse stopped working, when you try to run the command

`/var/discourse# ./launcher rebuild app` is an error.

` Error response from daemon: driver failed programming external connectivity on endpoint app (fc5fe43d9a3baadebc8c50fe62b740c08a65fe197697f6fb10e010541e390474): Error starting userland proxy: listen tcp 0.0.0.0:443: bind: address already in use.`

When trying to enter the site, I get the error “SEC\_ERROR\_EXPIRED\_CERTIFICATE”
