I would try restarting your docker instance. It might be a glitch or a bug that can be fixed by restarting.

acaonweb · January 7, 2026, 10:23am

i’ve done it, pulled down the container. the problem remain

achamm · January 7, 2026, 11:49pm

It’s possible something wrong with the cloudfare tunnel, can you try with a diffrent provider?

acaonweb · January 9, 2026, 5:37pm

no, I can’t, but why all my web hook through cloud flare are working?

Just a question to try to resolve: btw, form was working a couple of versions ago

At least then we can narrow it down to a version issue possibly. Is the webhook URL set in the local config file?

if your ever able to change providers, i reccomend tailscale funnel, its free and works just like cloudfare. Try to check your browser console when pressing the trigger, it will tell hyou if there is errors.

None of the forms work either on my self-deployment.
Version 2.3.1

CF-showing tunnel is healthy, and it is working as usual EXCEPT for the forms just spinning and throwing the below console errors.

yes, except forms, everything is working.. web hooks, chat url, everything except forms

I would see if you can maybe download the workflow and downgrade your version.

I paste here my docker compose, maybe someone find something wrong. But forms were working before, with the same composer
