What Heroku CLI commands are useful for troubleshooting SSL issues?

Several commands are helpful: `heroku certs:info` (displays certificate information), `heroku domains` (lists configured domains), `heroku domains:remove` (removes a domain), and `heroku certs:add your_certificate.pem --key your_key.pem` (adds a custom certificate). Also, `heroku logs --tail` can reveal errors related to SSL during app startup or requests.
