Hello,
One https website not working through our Cisco Router 2900 Series. If I connect directly to ISP without router that website working good. I didn't changed any configuration recently, except IOS upgrade to c2900-universalk9-mz.SPA.157-3.M8.bin. Any idea about this problem.
I am not expert in cisco devices.
Thank you

i would compare the config before and after the upgrade? I do not see any reason for only 1 website you mentioned ?
what is that website, from Device are you able to resolve DNS, then should work as expected. Maybe this required wireshark packet capture.

Hi Balaji,
Thank you for your reply.
This website not working for me "https://isg.edu.sa". before this was working for me. I compared before and after IOS upgrade configuration, both looks same.

Thank you

Hi Balaji,
Yes, I am trying to access from my PC.
From router I can ping to isg.edu.sa, but I can't able to ping from PC.
Thank you
