Reopen pullreguest: No new commits in branch

Hi

I had some problems to revert accident merge sun of my branch.

Did many things I can't even recall anymore, but it seems that my branch is now in state I want it to be.

It seems that some of my actions set PR to closed state. I have force pushed commits to different states but I'm not able to reopen PR.

Tried with this: https://openwrt.org/docs/guide-developer/working-with-github-pr#reopen_closed_pr
and many other instructions but I feel like my branch has lost link to PR.

PR I'm trying to reopen:

I'm out of ideas how to proceed? Any tips or tricks?

Weird enough it seems that openwrt checks for PR gets triggered:
