I am connecting to my Synology NAS via the LAN IP. Some services on the NAS are accessible via the internet. The certificate installed on the NAS is linked to my external domain name; not the internal LAN IP range.
If change the IP in the FTP Client’s settings to my external domain name, then I get an ‘connection refused error’ for my external/WAN address. I tried granting access to both the SFTP and FTPS services, by adding my external IP adress in the NAS’s firewall, but still get the connection refused error (also after restarting the FTP Client).
Not sure whether it is relevant: I also use FTPS with another Homey app (Exporteer/Archive Insights) and that allows me to establish a secure FTPS connection to my LAN IP, without any certificate issues.
Any suggestions how to get the secure connection working?
