Snap refresh does not work

Hi all,

I am new to Ubuntu. Currently, I am using Ubuntu with Snap.

The command ‘sudo snap refresh’ is working fine till recently it fail to work. Attached is the screenshot of the error that was produced when running this command.

It fails to work when I connect to my wifi. However, it is working fine when I connect my laptop to my mobile hotspot. I have contacted my ISP to reset my port but it still fails to work.

What should I do now?

Your help is highly appreciated.

Thanks.

snap version
snap changes
journalctl --no-pager -u snapd
