FVS336Gv2 Secure Connection Failed
System Name: FVS336Gv2
Firmware Version: 4.3.3-6
After upgrading firmwear to4.3.3-6 when I try to access admin interface I get an error in all browsers I have tried "An error occurred during a connection to 192.168.1.1. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL"
I havew tried factory reset and updating firmwear again but same error.
Is there a way to fix this or is this product a brick?

Hi webspider,
Kindly answer the questions below:
a. Have you tried to clear the cache on the browsers you're using then try to access again the web-GUI of the FVS336Gv2?
b. Have you tried using another PC/laptop to isolate the problem?
If ever you are using Firefox, try this: go to Preferences > Advanced > Encryption > View Certificates > Servers > Add Exception. Then enter the IP address of your router, (for example: HTTPS://192.168.1.1), then click Get Certificate > Confirm Security Exception. Let us know if this helps.

Hi DaneA
Yes the first thing I did was clear cache and history I also deleted the certificate for https://192.168.1.1 and tried to add an exception. Firefox 51.0.1 simply refuses to add the certificate.I'm using ubuntu at my work where this FW was in use. I decided to bring the FW home for more tests and my laptop has the same problem.
I can access the FW admin with Chrome but it reverts to a non secure mode. I have tested it now with an Widows XP machine and Firefox complains the certificate is not valid but it will allow me to add an exception.
That does not solve the problem though. The issue is the certificate and serial number don't match. "Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL"
This happened after I updated the firmware, is it possible the wew firmware has a bug that effects the certificate?
