Hi, I upgraded the firmware from 17.5.12 mr2 to 18.05 but now i can not access the web admin. Only user portal working on hidden mode browser. What can you advice me to reach the admin interface?.also i couldnt login with ssh.
Please connect device with serial console cable and rollback to previous firmware version 17.5.12 mr2 then 17.5.12 MR12 upgrade to 17.5.16 MR 16.
If Device is in the failsafe mode, you might…
Try plugging into the console port.
Thank you, so isn't there anything I can do remotely. do I need to pass to the site? :/
no, because you need to login to roll back to the previous version. Also I don't think you can go from v117.5.12 to v18.0.5. From memory you need to be at least on mr14 or mr15.
