Cannot initiate the connection to archive.ubuntu.com:80

this issues had been in my life for 2 weeks and i was unable to figure it out. My domain name was hosted by 1&1 and my website is hosted by my own ubuntu 18.04. I have no issue to ping anywhere and my website has no issue to visit. However I cant update or upgrade my Ubuntu server with the following error message: my nameserver shows this: nameserver 127.0.0.53 options edns0

Thank you in advance for help.
