You can renew an expired proxy certificate directly via the Bridge user interface.

1. Go to the Certificate tab of the corresponding proxy node,

2. Click Create New Self-Signed Certificate.

   

   A message 'Created new certificate. ... ' informs you, that the certificate has been created.

   The new self-signed certificate will be created without further request for confirmation - existing certificates (also ones signed by a certification company) are overwritten.

3. Restart the proxy to enable the new certificate.
