I guys,
I have 2 errors in my logs that I can’t fix myself. They are both related to SabreDAV it fail to connect through :
port 443 :

This port is open (I connect to nextcloud through https with a letsencrypt certificate). Not directed binded to nextcloud’s server, but to a nginx proxy front-end.
port 8064 :
{"reqId":"wBLTE7plrM3yPfz5ZDF2","remoteAddr":"xxx.yyy.zzz.aaa","app":"core","message":"Exception while scanning storage \"shared::aea399be83d7c34d6aca8149412b981d\": Sabre\\HTTP\\ClientException: Failed to connect to 127.0.0.1 port 8064: Connection refused","level":3,"time":"2017-03-06 21:27:03","method":"PROPFIND","url":"\/remote.php\/webdav","user":"myuser","version":"11.0.2.7"}
Any idea what is that port ?
This port is closed and I can’t find anything about it.
I didn’t notice any problem while using nextcloud. Everything seems to works, but these errors comes very often and it’s not clean !
Any help is welcome
