CO-piBot: return = 19 : SELF SIGNED CERT IN CHAIN
Self-signed certificate in the certification chain

This code indicates that the certification chain contains a certificate considered as self-signed.

Seeing that we do not deliver self-signed certificate, it means the certificate that has been found does not come from us but has been self-generated by the server software.

If you installed our certificate, there is a configuration mistake. It can be caused by:
  • server has not been rebooted to take the modifications into account
  • a configuration modification that is not active
  • mistake in the modification
  • etc.

We invite you to check each one of these points, to consult your software manual and if needed, to contact your software support. Install a server certificate

Possible scenarii

Import the certification chain manually

On microsoft platforms, you may not have imported the .p7b file provided but only the .cer one.

This may mean that the server has generated its own security credentials, which Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You should not proceed, especially if you have never seen this warning before for this site.
