DS 220+ "Connection failed. Please check your internet connection"

[Lifek]

Hi, I'm new here. I've got a new DS220+ NAS which I unfortunately can't connect it to the internet.


# Problem: I get the message "Connection failed. Please check your internet connection" in various flavors.

Control Panel > Update & Restore > DSM Update > Status: "Connection failed. Please check your internet connection"

Control Panel > Synology Account >Popup: "Unable to perform this operation, possibly because the network connection is unstable..."

Package Center > Popup: "Connection failed. Please check your network and time settings..."

Regional Options > Time Settings > Synchronise with NTP server > Status: "Normal" (!!!)


# What I want

I want to a) be able to update my NAS and b) download some packages for a self-hosted setup (docker, git, paperless, ...)



# Things I tried

• Manually updating the DS to the latest version
• Every combination of DNS servers (in the router and in the NAS).
  • I tried all variants of 8.8.8.8, 8.8.4.4, 1.1.1.1 and 9.9.9.9.
  • I also tried the internet provider recommended one
• The steps on
  • Why can't I connect to Package Center? - Synology Knowledge Center,
  • Problems connection to NAS Control Panel via ethernet,
  • I encountered the "connection failed" message. What can I do? - Synology Knowledge Center and
  • Handling the Dreaded Synology DSM 'Cannot Connect To The Internet' Error
• Random steps I found on the internet or in the forum. Unfortunately I lost track of what I tried..
  • For examples things from Problems connection to NAS Control Panel via ethernet
• Logging into my NAS via SSH and ping'ing all the addresses listed on What websites does my Synology NAS connect to when running services or updating software? - Synology Knowledge Center
• Restarting
• I also tried using the web GUI from different browsers and PCs
• I also I ran all the commands on a PC that is connected via ethernet to the router. Didn't notice any problems

Finally, as I can update the date/time, I believe this to be a DNS problem. I ran some random commands, but I have no idea what I am doing here..

it appears as if pinging to the Synology servers via CLI works. But in the GUI I still get the errors.

FYI - I checked my NAS (DS-918+) this morning status is now being reported correctly. It appears the upstream issue (reporting: "connection failed. Please check your internet connection") has now been corrected. Many thanks for helping me to understand the issue and to "do nothing" while the upstream error is corrected.

Works for me too now!

This just starting happening to me today a few hours ago. Wondering if it's the same thing because I cannot enable quickcionnect, I can't access Synology Account, Support Center, Package Center, too much to name. But OP sounds very similar to what I'm encountering. None of the normal suggestions have helped and I can ping everything on their url list
