Had a problem with SSL (that's solved now), and a suggestion for the hosting docs

[heikadog]

I've already set up my labeler with no current problems, but one of the things I had a problem with when I set up my Ozone instance was setting up Caddy. I followed the instructions to the T (checked them multiple times and did it multiple times, even checking my command history and making sure I formatted the Caddyfile correctly), but Caddy wasn't working. I talked to someone else who runs a labeler and they told me to restart Caddy after they saw I had an SSL error, which did work. Adding this command to the hosting docs (maybe with an [!IMPORTANT] tag and some additional text explaining "if you're having problems with Caddy, try restarting"?) may be of use for people who have SSL problems after they set up their Caddyfile:

docker restart caddy

Caddy ended up working fine after I ran this command, but for people who might not be as technically-inclined for setting up labelers, this might pose an issue.
