Hey, I still have problems with Duplicati on my DS216j running DSM 6.2.1-23824 Update 4. I use Mono 4.6.2-0096 and Duplicati 2.0.4.5. And my user is member of http group. So looking at the Threads I found so far here, I should not get the “Connection lost” error. Any idea?

Still not working at Synology DS216j

I assume you confirmed that the user is part of the HTTP group as suggested in the Troubleshooting section of the How-To guide?
