Hello!

I've been trying to solve a weird networking issue and hope to find some help with it.
The other day I changed the motherboard in my server due to a PCIE-issue and after the usual tinkering everything seems to work fine now except I'm not able to view the apps list and my docker containers also don't seem to be able to connect to the internet.

 

From the Apps tab I get the following error:

Download of appfeed failed.

Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of 208.67.222.222 and 208.67.220.220 and try again.

Alternatively, there is also a chance that the server handling the application feed is temporarily down. See also this post for more information
Last JSON error Recorded: Syntax error

 

I tested different DNS-servers (OpenDNS, Cloudflare, Google, etc.) but nothing seems to change.

Ping and manual resovling seems to work fine:

So I did a "reset" on my networking config, meaning I deleted the old network.cfg from /flash/config, rebooted and tried again, nothing changed.

 

I assigned a fixed IP chained to the MAC-adress of the new motherboard, didn't help.

 

So I'm stuck, I hope someone can point me in the right direction, I've attached the diagnostics zip below.

 

Thanks in advance!

Yes, seems to work fine:

I'll need to see CA's diagnostics

 

• Apps, then Settings
• Enable Debugging and apply
• Back within CA after the message reappears click the Debugging link at the very bottom

 

Doubt it'll say anything other than it was unable to download the feed, but you never know.

Thanks for helping me this far!

 

See the diagnostics output attached. One interesting thing I found while flying over it is that the date seems to be off, also Unraid shows a 3-year plus system uptime which is nowhere near possible.

Yeah, that is going to be your entire problem.  Both the logs and CA's diagnostics show that the date is March 15, 2019 and SSL fails if the date is significantly out for security reasons.

 

Settings - Date & Time. set the correct date & time and also give the system a couple of ntp servers

That seems do have done the trick! That was not what I expected it to be

 

Thanks a lot!
