Hello,
This issue is already known to our developers and is expected to be resolved in the upcoming 7.20 firmware release.
As a current workaround, if the “Renew” button does not function as expected, you can manually regenerate the WebUI server certificate by running the following command:
api POST /access_control/webui/actions/generate '{"data":{"force":"1"}}'
Alternatively, if the first suggestion wouldn’t help and you are using other certificates (not uhttpd.crt) for HTTPS connections, you can try the following steps to renew the expired certificate:
- Disable the Redirect to HTTPS option in the HTTP configuration settings.
- Configure the system to continue using the expired certificates for HTTPS.
- Access the WebUI using the HTTP protocol (otherwise, the interface may remain inaccessible).
- Once logged in, the renewal notification with the “Renew” button should appear.
- Click “Renew” to regenerate the expired certificates.
Best regards,
