Collabora stopped working on two of my instances, failed to load document

I’ve spent some more hours by trying around, especially as I have - or better had - one working NC instance. Tracking the differences I’ve found that the only one was that the working NC instance was sitting behind an older HAPROXY version than the other ones.

I’ve updated that HAPROXY and it stopped working here as well :frowning:

So Collabora introduced an issue with 6.4.10.x in case the Nexcloud instance is handled by HAPROXY >=2.x.

I’ve opened an issue: https://github.com/CollaboraOnline/online/issues/3199
