Nextcloud will only download files

Hey there, I am running nextcloud in a docker for a few years without much of an issue but have ran into one now. I've only been able to download files for the last few weeks, can't directly edit within nextcloud. I've tried tons of troubleshooting and testing and have not been able to resolve the issue. I have toggled off my collabora server connection and re-enabled it, shows green and valid and good to go. I am able to successfully test collabora independently so not really understanding what the cause is. I thought it may be file permissions but have tried to reset them as well as create new folders/files without issue, but still can't edit from within nextcloud. I've googled a bit on the topic and haven't found anything super relevant. Anyone ran into this before?
