cisco router, error NET::ERR_CERT_AUTHORITY_INVALID

  • 772

I have a cisco router RV215W less than one year old, and I do:

$ wget https://192.168.2.254/
--2017-03-02 10:26:52--  https://192.168.2.254/
Connecting to 192.168.2.254:443... connected.
ERROR: cannot verify 192.168.2.254's certificate, issued by ‘serialNumber=PID:RV215W-E SN:CCQ20150HG1,CN=10:BB:18:AB:71:21,OU=Cisco Small Business,O=Cisco Systems\\, Inc.’:
  Self-signed certificate encountered.
    ERROR: certificate common name ‘10:BB:18:AB:71:21’ doesn't match requested host name ‘192.168.2.254’.
To connect to 192.168.2.254 insecurely, use `--no-check-certificate'.

I didn't have this before. I cannot tell the IOS version right now since I don't have access to the router interface (unless I log using HTTP and not HTTPS)

If I log from the browser, I get

NET::ERR_CERT_AUTHORITY_INVALID

  1. The answer is in your post/question.

    Try wget --no-check-certificate https://192.168.2.254/

    wget tries to check the shown cert, which is obviously self-signed.
