WRN Waking up dead poll thread [HttpSynReqPoll]

I see this in the loolwsd logs when I try to view a document in my Nextcloud site

WRN Waking up dead poll thread [HttpSynReqPoll], started: false, finished: false| ./net/Socket.hpp:680

The nextcloud page ends up blank with no errors in the logs.

Any ideas?

This seems to be an issue in the latest build(s). works, does not.

Hrm, I installed via my package manager I think. Not sure how to downgrade.

@logart, if you open browser console, do you see any errors there?

This seems like the same issue:

This is now fixed, please update your packages.
