RBR50v2 self-signed certificate rejected

Hi,

 

I use an Orbi router RBR50v2 with 2 satellites and they work as expected. Problem is when I try to access the admin page, for example:

 

https://orbilogin.net/index.htm

 

Safari rejects it as it says is not secure ( I've imported the certificate in keychain and trusted, of courwse ), even after confirming I want to access twice. Chrome rejects the page with ERR_SSL_KEY_USAGE_INCOMPATIBLE error. Only Firefox allows access by now.

 

I suppose that newer browsers impose more checks to certificates, so I think it's Netgear to update the router firmware to create an useable certificate, or at least provide the way to update it...

 

Any idea ? Should I start thinking on a new network infrastructure ?

 

Regards,

Joan

    Your analysis is correct that modern web browsers have become paranoid about two types of web sites:

    • unencrypted (http) web sites.  Not using encryption means that anyone in the network between the web browser and the web site could potentially view the contents.
      What the web browser does not take into account is that the Orbi web interface is on a router on the local network, and thus it is impossible to 'snoop' on the communication.
    • encrypted (https) web sites that use self-signed certificates.  With no SSL "authority" to vouch for them, the web browser is afraid that someone could be pretending to be orbilogin.net.
      Once again, what the web browser does not take into account is that the IP address of orbilogin.net was not resolved by a DNS server, but was rather intercepted by the router itself.

    There is almost always a means to tell the web browser to "ignore this issue and proceed to the web page".  I use Chrome, Edge, Firefox, and Opera with the Orbi RBR50 every day.

      How do you get Chrome working with the Orbi RBR50 ( v2.7.5.6 ) ??

  • I've been able to use Chrome finally, first importing the router certificate as trusted and using the URL with hostname like https://orbilogin.net... With ip address I still get the error. I've swtiched off the option to access the router with HTTPS only in RBR50, and Safari is able to arrive to login screen now with the ip address. But after login, I'm redirected to https:// so error again in Safari. I've a router restart pending to see if the 'access router with HTTPS only' option requires it.

    When I attempt to access the http version, this message pops up and I select "Continue to site"

    When I attempt to access the https version, this message pops up and I select "Advanced"

    and this comes up.  I select "Proceed to orbilogin.net"

    This is on Windows 11.  What happens on MacOS is always a mystery to me.
