Text editor loses connection regularly

[JordanDIG]

Nextcloud version: 23.0.2
Operating system and version: Raspbian

I am using Apache2
PHP version: 8.0

The issue you are facing: If I edit markdown documents via the embedded web texteditor, it loses regularly the sync:

file could not be loaded. Please check your internet connection (retry)

This occurs right after a few minutes and I guess a tip faster if you are on a edit.
This error occurs on different internet connections.

Steps to replicate it:

Open Files app on your cloud webinterface
Click a textfile to edit
Start writing to the opened file and wait till the above poppup message appears
Click rety and note, that nothing will reload. So reload the whole page

I have this same issue running on my Asustor NAS

I am seeing this too but I'm not sure what the cause is. I've put what debugging I've done so far in https://help.nextcloud.com/t/text-editor-loses-connection-regularly/96787/5.

EDIT: the cause, for me, was this cron entry I added to support renewing my letsencrypt certs:

*/5 * * * * systemctl restart nginx

🤦

But I think there is still room for improvement here: richdocuments (the Collabora editor for .ods,.odt,.docx,.xlsx, etc) doesn't suffer from this. It gives errors in the Javascript console while nginx is restarting but only for a few seconds; after, it reconnects and functions fine. No one on my site ever noticed there was a problem.

But this app shows this prompt

and stops working until the user intervenes. It's not the end of the world, especially now that I know the cause and I've throttled way back on how eager I was to reset nginx, but it could be better.

Could you keep the "Offline, changes will be saved when online" text, but drop the button; instead, just show a loading spinner that retries and retries (perhaps with exponential backoff) until it reconnects?
