Some Retool apps cannot save, on self hosted retool

I am currently using retool self-hosted. I am currently the only developer and user, so I am on the free plan.

However I suddenly find some of my more complex apps cannot save, while some of new created apps can still save.

I found lots of 5xx in browser console.


But I can open, use, and edit the app without problem, just cannot save.
I see one request with url:
http://120.26.195.97:3000/api/pages/uuids/eec210f4-392f-11ee-a417-f3c5cf20efda/save

The request got an error:

{"success":false,"message":"Authentication failure. Missing xsrf token"}

I tried reinstall retool totally from an empty vm, upgrade to 3.33.21-stable, still not working.

I checked other posts on this issue mostly because of payment plan. But it seems not the case for me.

Please help.

I ended up starting a brand new vm. It works now. Still no idea what's the problem..

Hey @Peifeng_Zhang glad you got back up and running with a new VM. Based on this information, I'm also not sure what the underlying issue was. But to confirm, the apps all now save, and you haven't seen the issue crop up with the larger apps again?
