Hi, since my migration to a new server I´m getting 412 errors at my web browser console from time to time at loading the file list or when I am writing a note: ``` files.js?v=8a34a280-10:51 POST https://cloud.xy.de/apps/text/session/sync 412 (anonymous) @ files.js?v=8a34a280-10:51 e.exports @ files.js?v=8a34a280-10:51 e.exports @ files.js?v=8a34a280-10:51 Promise.then (async) c.request @ files.js?v=8a34a280-10:51 r.forEach.c. @ files.js?v=8a34a280-10:51 (anonymous) @ files.js?v=8a34a280-10:51 value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.catch (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 Promise.then (async) value @ editor.js?v=5145bf0dbc6192145c28:23 setInterval (async) value @ editor.js?v=5145bf0dbc6192145c28:23 (anonymous) @ editor.js?v=5145bf0dbc6192145c28:23 editor.js?v=5145bf0dbc6192145c28:23 Failed to fetch steps due to other reason Error: Request failed with status code 412 at e.exports (files.js?v=8a34a280-10:51) at e.exports (files.js?v=8a34a280-10:51) at XMLHttpRequest.d.onreadystatechange (files.js?v=8a34a280-10:51) ``` I don´t know what I could have missed.

I do get the same 412 errors from my instance. It’s making me crazy. Happens while editing markdown files in the “Notes” app. ---

No solution to this? I have to paste text into my Markdown files because editing them is impossible. ---

Problem is still persisting for me. Currently on Nextcloud 21 running on Apache. It makes using the Markdown editor really difficult, because it randomly fails after a while. I looked at the difference between the requests, when they’re working, and when they fail (due to HTTP 412). Seems the only difference between them is in the cookie. While the requests succeed, there is an entry in the cookie like this: `ocfi1sfm2880=dht2tl7djsh9812aqbsubn6unb` This is completely missing, in the requests which fail due to 412. ---
