Hi Nuno_xzorp,

 

When you connect your bigip device via console, do you see any errors in /var/log/httpd/httpd_errors logs?

Please make sure https service is working on bigip device.

 

Have a nice day.

Hi oguzy,

I checked that but don't see any error.

Meantime I found the mgmt port mac-address last digit is diferent from listed on switch arp entry, not sure if this have influence because I can ping and reach via ssh.

Thanks

    Hİ Nuno_xzorp,

    As you said in your first post, you could not login via ssh due to wrong credentials. In the second post the mac address is different in the arp record. Could you please make sure you try to connect the right device? I mean after power issue, the bigip may get a new IP address. Please connect via console again, and check your IP address of bigip device. If it is the same IP with the address you are pinging, then check your listening port in your bigip device via netstat command and share with us the result.

    netstat -ano | grep LISTEN | grep 443

    Hi Nuno_zorp,

    Ok, the bigip listens on port 443. Could you please try to reach from terminal of your local PC to bigip via telnet?

    telnet bigip_IP 443

    If the output of telnet is connected, then we can say we have layer4 connectivity. Also, if you use proxy in your browser settings, please disable it and try to connect https://bigip_IP

    Hi oguzy,

    Thank you for reply.

    Yes, the ip address is the same, the result of the command is:

    tcp6    0   0 :::443         :::*          LISTEN   off (0.00/0/0)

     

    thanks for letting me know.

    Sorry, think I created below a new post and not a reply, just to add that for port 22 it opens, as I said in the first post (ssh) so it looks like for some reason port 443 is not working
