Hello,

 

my certificate expired. Now I cannot access the controller anymore.

Firefox does not allow me to continue (according to HSTS specification).

Chrome allows me to continue but does not load the controller interface.

 

How would I replace the certificate?


Thank you,

I managed to replace the certificate via Firefox private window. That one allows to proceed on expired certificates and loads the page fine.

@Kevin_Z and @Vincent-TP ,

 

thank you for marking my comment as the solution.

 

I think there should be a different way to replace the the certificates OOTB. Otherwise users can lock themselves out of the controller.

Even Mozilla's stance is not to allow skipping the expired certificate warning as HSTS specifications do not allow it. So they might remove it one day.

 

Best wishes,

  @Vincent-TP I just checked the thread and I don't think this is the same.

My request is the overall the danger of a system lockout if a certificate expires. Irrelevant of the provider.

 

We need a method to replace a certificate if it has expired. Browsers and specifications do not allow access to websites with expired certificates provided via a HSTS connection.

 

So maybe like an emergency API/page to reset the expired certificate and provide a new Omada certificate.
