Session Pale Ale keeps souring

[Brewer #453390]

Looking for any tips or advice! I make a variety of beers, casked bitters and pales, kegged NEIPAs, no issues. However, I've attempted a kegged Session Pale several times and it keeps souring after a few weeks in keg. Any ideas why this is happening? Cleaned and steamed everything as normal, no sign of this in other beers so struggling to work out why!

thats unusual.

post the recipe, water, etc.

is it the same draft line? when did you last clean/replace your lines?

Is it one particular keg, or fermenter?
Is there something different about your process for this beer than all the others (whirlpool/dryhop/racking)?

Without a reply, I believe Mia started brewing again?
