Appointment booking is not completed successfully

[pax77-dd]

Hello,
The appointment booking has not been working for some time, I can't remember when. I suspect that it is due to an update of nextcloud or the app, as I installed the app some time ago and it was stable.
Here is the error description:
After filling out the form fields, checking the GDPR box, the result is an error message; “An error has occurred. Please try again later, thank you.” Previously, the information page for e-mail confirmation of the appointment appeared in this process step.
How can I fix this problem?
Kind regards
Remo

Can you check Nextcloud logs ? Are there any errors related to appointments ?

Also, usually an error URL look like this https://your.domain.com/apps/appointments/pub/d1A0PL_xSItmGXjB0A2/form?sts=2&d=... , what is the digit after form?sts= in your error page URL ?

I am having a similar issue. The error received is "An error has occurred Please try again and select a different date."

Previously a date/time was available in the date dropdown which was not on the calendar. Selecting this caused issues.

In the logs I have the following. The remote address XXXX is of a user, and YYYY is me checking on android.

Previously I was receiving an error on Firefox saying that the page could not be displayed as it was embeded on another website. I have checked and removed the embed from another page on my website. I have also re-created the form but when testing either directly on the preview, or embeded I receive the same error to try another date.

I will attempt to remove and re-add all the dates in the calendar and report back.

Additionally, I believe this was all working until I stopped sharing (disabled) the form the other day. The issues seem to have come up since re-enabling the form.

This seems to have been solved after updating nextcloud, removing all open appointments from the calendar and re-adding them with the simple timeslot mode.
