Somehow my netdrive3 got messed up. I have two NAS. The first one uses WebDAV through router port 5006 (internal port 5006). The second one is supposed to use WebDAV through router port 5016 (internal port 5006). I have two separate dynamic DNS addresses to reach the two NAS.
When I configure the second one, it ask me to check the internet address again an refuses to accept https://dynamic_DNS2.org:5016.
This used to work for years without problems. Any suggestions?
The issue you described is most likely caused by one of the following:
SSL certificate issue on your Synology NAS
The SSL certificate may be expired or the domain name on the certificate may not match your DDNS address (https://dynamic_DNS2.org:5016).
Please open the address directly in your web browser and check whether you see any “SSL security warning.”
Blocked IP address on Synology NAS
If Synology’s “Auto Block” feature (Control Panel → Security → Protection → Auto Block) has blocked your PC’s IP address,
NetDrive will not be able to connect.
Please check the Auto Block list and remove your PC’s IP address if it appears there.
