I just spent two days troubleshooting this issue so I felt I should probably share it.
In an attempt to solve some stringing issues, issues I swapped my nozzle, I had been printing Petg for the first time in years so it probably got stuck and prevented the nozzle from going all the way in. This likely solved my stringing issue but created a new stringing issue. I finally fixed it by unscrewing the nozzle and then reinserting it at 240°
Just wanted to share so y’all can hopefully learn from my mistakes
Unscrewing the nozzle cold can also strip the threads in the heat block.
