SOLVED - Cannot accept calendar invitation

#1

New installation, Nextcloud 15.0.5
I’ve got everything set up and working well, but I’ve run into a problem with the calendar. If I create a new appointment and add an attendee, an email get sent. (in this case to a gmail address for testing) The message has an “Accept” button that contains a link to my server. But when I click the Accept button, I get an error page saying, “There was an error updating your attendance status. Please contact the organizer directly.”

I’m not sure if this is a bug or a configuration problem on my system. I don’t see anything in the logs to help me troubleshoot the problem. Any suggestions?

Thanks.

Error updating event participation by invited attendees in calendar

Solved - I had created two nextcloud users (the admin user and myself) with the same email address. After changing the address of the admin user so that all users had unique addresses, my invitations can now be accepted.
