Yes, it’s a duplicate of #523. Please follow up there.
Maybe someone can provide detailed steps to reproduce so that I can have a look at the issue?
I’ve opened an issue on the nextcloud GitHub HERE
Relevant details can be found in the Issue, or I can duplicate the issue here at request.
Very likely a Web server configuration problem (like suppressing
ETag in the Web server config or something like that).
@rfc2822 would you recommend anything specific to check?
I’ve disabled mod_deflate for the entire nextcloud subdirectory, as I’d read that it can cause issues, but the issue remains…
I’ve also searched through the master configuration file for anything related to ETags, and can seem to find anything relevant.
@rfc2822 update. It’s JUST the calendar that fails to sync. If I uncheck the calendar, the error goes away entirely.
@nate2014jatc Maybe you could ask in the Nextcloud forum. As far as I know, issues are better for reporting bugs than asking questions, and it will take longer to get an answer.
