first I am trying to share a big directory with someone thru the share link but after 2 gig the transfer stop and the link become obsolete with:
"File not found
The document could not be found on the server. Maybe the share was deleted or has expired?"
the other issues are Nextcloud- settings overview configuration waning in orange
There are some warnings regarding your setup."
- The reverse proxy header configuration is incorrect, or you are accessing Nextcloud from a trusted proxy. If not, this is a security issue and can allow an attacker to spoof their IP address as visible to the Nextcloud. Further information can be found in the documentation ↗.
- The "X-Robots-Tag" HTTP header is not set to "none". This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.
- The "Strict-Transport-Security" HTTP header is not set to at least "15552000" seconds. For enhanced security, it is recommended to enable HSTS as described in the security tips ↗.
