Since the upgrade from Nextcloud 19 to 20, documents can no longer be opened with Collabora Online. I have discovered the following error message:
2020/11/10 08:37:38 [error] 11475#0: *97066 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: XXX.XXX.XXX.XX, server: www.mydomain.com, request: "GET /apps/richdocumentscode/proxy.php?req=/hosting/discovery HTTP/1.1", upstream: "fastcgi://unix:///var/www/vhosts/system/mydomain.com/php-fpm.sock:", host: "www.mydomain.com"

Looks like there is a problem with the PHP-FPM socket. Can anyone help?
