Problems reaching servers with DDNS no.ip.org

[PincoPalla]

Hi everyone, since this morning I have problems reaching the server from the DDNS XXYY.no.ip.org someone else has the same problems ??? It gives me that it is impossible to connect to the server, verify the connection, luckily I also registered a DDNS at XXYY.duckdns.org and for now I use that but I don't understand why the first one doesn't work anymore. Thanks

It is working over here...

Here I have the same problem:
DDNS provider NO-IP.com was configured on XPEnology DS3615xs with V1.03b bootloader
(Actually, it is still configured and working)
But...
When through the "Control Panel" I go to the "Remote Access" tab - I see: "It is impossible to connect to the server. Check the server's network connection)
Meanwhile, DDNS performs its function.
What did I do:
1. Followed instructions from Synology.
2. Deleted and re-created the DDNS function (from NO-IP.com) a) with the same settings, b) with the settings of another NO-IP.com account
Nothing changes!
Meanwhile, if I connect a function from the Duckdns.org provider, then everything is correct and displayed and works.

I also have a legal NAS Synology.
So on legal - the NO-IP.com service works without errors. (Same settings)
Advise - in which direction to dig? Can I somehow clean the cache on XPEnology? Or something else to do?
Thanks in advance.

Solution of the problem:

 

# ssh to your NAS first
sudo -i
mv /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt.bak
curl -Lko /etc/ssl/certs/ca-certificates.crt https://curl.se/ca/cacert.pem
 
That's all !!

Yes hi it's the same problem as me, at the beginning nothing worked, I didn't reach the server and all the services (connected with that DDNS) today still gives me an error but all the services work

 

then I try your solution

Excuse me again, with this solution what can you do ??? (cache reset or other ??)

As soon as the procedure as indicated by Ostap60 has been carried out, the DDNS is back to work correctly. Thank you all
