Jetpack – Publicize broken

Hi,
For last few months Publicize option in Jetpack on my blog was broken. I couldn’t add new connections. If tried to connect it to my Fb or Twitter, it would immediately break connection to WordPress.com account. I asked the support to look at it. They couldn’t find the root cause.
Now with the help of my hosting provider I reset my hosting account and freshly installed WordPress. Jetpack works fine. However, if I restore or reuse my old db then it again crashes. Same error.

Which table could be causing this issue? I tried using WP’s import export tool. If I import-export all contents then the same problem comes up.

TIA
