Certificate error appears upon visiting the controller page.
Errors like this may appear without a valid SSL certificate when visiting sites on HTTPS.
Possible causes / recommended actions
- Missing a valid SSL certificate.
UniFi relies on HTTPS for extra security. This means that the browser will check for valid certificates when making a secure connection to the web server. Although the alert message may prove annoying, there's no risk to the connecting user. To avoid this error:
- Buy a signed SSL certificate from any web hosting provider.
- Then make the following changes to the controller:
sudo su - # cd <unifi_base> # on Windows, "%USERPROFILE%/Ubiquiti Unifi" cd /usr/lib/unifi # create new certificate (with csr) java -jar lib/ace.jar new_cert <hostname> <company> <city> <state> <country> # your CSR can be found at /var/lib/unifi # - unifi_certificate.csr.der # - unifi_certificate.csr.pem # have this CSR signed by a CA, you'll get a few certificates back... # copy the signed certificate(s) to <unifi_base> # import the signed certificate and other intermediate certificates java -jar lib/ace.jar import_cert <signed_cert> [<other_intermediate_root_certs>...]
Note: once you have created the CSR it can be found in the %USERPROFILE%\Ubiquiti UniFi\data folder. On Mac find it here: /Users/username/Library/Applic
Note: Not sure where to find <unifi_base>? See this article.
