Hello there,
I followed the steps at https://nextcloud.com/collaboraonline/. One difference: I have no certificate up to now, so I commented out all lines concerning ssl in /etc/apache2/sites-available/000-default.conf
My nextcloud runs well, but access to collabra does not work. Inside the Nextcloud, I get the following error:
[status code] 502 [reason phrase] Proxy Error
When I look at the error.log of my apache server, I see the following output:
[Wed Oct 19 11:35:16.720375 2016] [proxy_http:error] [pid 15549] (20014)Internal error: [client 85.214.72.28:36836] AH01102: error reading status line from remote server 127.0.0.1:9980
[Wed Oct 19 11:35:16.720465 2016] [proxy:error] [pid 15549] [client 85.214.72.28:36836] AH00898: Error reading from remote server returned by /hosting/discovery
I hope that someone can help me on this. If any other logs/infos are needed, please let me know.
