Custom SSL Certificates
The installer generates a self-signed certificate, so browsers show a security warning when you visit the appliance. To use your own certificate instead, replace the two files nginx serves:
/opt/sysward/sysward.cert— the certificate (include the full chain if your CA provides intermediates)/opt/sysward/sysward.key— the private key
Then restart nginx:
sudo systemctl restart nginx
The appliance now serves HTTPS with your certificate — no more browser warning, provided the certificate matches the hostname your users (and agents) use to reach the appliance.
Renewing? Overwrite the same two files and restart nginx again. If you automate renewal (for example with certbot), add the copy + restart as a post-renewal hook.
