Back office errors when saving

Questions

This has been bugging me for months on various sites, specifically when running locally. Often when hitting the Save & Publish button, it changes to an “x” and I get these in the console. There’s nothing in the terminal and no errors in the Log View.

This is just from clicking the button once:-

I’d LOVE to know what’s causing it as it making life working with Umbraco a bit of a misery when trying to enter content. I often get the three dots in the content pane, the content never loads and the page has to be reloaded to get the content. A total PITA.

I have the feeling it’s silently logged me out. Logging out and in again doesn’t fix it. The only thing that does is a site restart.

Browser is latest Brave running on latest Linux Mint Cinnamon, as is the site which is running from latest version of Rider.

Thanks

When I’ve seen 417s in the past its been something to do with the Umbraco backoffice session cookie being disrupted, might be worth seeing if these are being set correctly in the browser Cookies | Umbraco CMS (cookie consent configurations can sometimes be the culprit)

It appears that the UMB-XSRF-TOKEN cookie disappears after a short while unexpectedly when I open nodes for editing. It’s when this cookie is missing that the saves fail and the content pane’s don’t populate :frowning:

So I’m left with just two cookies: UMB_UCONTEXT and UMB-XSRF-V
