Please please give your login account next time which saves a bit of time figuring out which ones has to be diagnosed. Eventually I found it via the parent task on T356645#9522774 which states:

You look still to be blocked on wikitech https://wikitech.wikimedia.org/wiki/Special:Contributions/Conniecc1 - not sure if that's related but it should probably be undone

From the block log you got unblocked:

09:18, 8 February 2024 Jelto talk contribs block unblocked Conniecc1 talk contribs (per discussion in https://phabricator.wikimedia.org/T356645)

But that clearly did not get you unblocked from Gerrit for whatever reason:

Unblocking on wikitech should trigger a MediaWiki hook to reactivate the user in Gerrit. That got enhanced on Feb 1st by a0fa149e8e06d1954c6c36121eaf4e347e4d1f19 for T307558 . Maybe that previously broken or that patch broke it. I will dig into it and follow up on the other task.

Mentioned in SAL (#wikimedia-releng) [2024-03-13T08:31:11Z] <hashar> gerrit: reactivated account Conniecc1 using gerrit set-account 7450 --active | T360006

To address the root cause of the Gerrit user not being reactivated when the accounts is unblocked from Wikitech, I have reopened a past task and posted my analysis on it T307558#9625736.

@hashar Thank you so much! It works now!
