unable to pair Anova Oven with Anova

Hi,
I missed the Firmware Upgrade couple a year ago on my Anova Precision Oven
Since than I could not able to connect to the Anova App.

I have tried my different way but without much success. It was working well prior to this firmware upgrade.

Is there anyone who have this problem and way to get it works?

I have even seek help with Anova Support, but they could not help.

Appreciated if you would share the solution with me.
Thanks.
