I was able to fix the issue with the following procedure:
1. Edit /etc/systemd/system/snapd.service.d/snap_layer_proxy.conf
2. Put the "no_proxy" Environment on the last line of the file instead of the first
* on "working nodes", it was on the last line
* on "failing nodes" it was on the first line
3. sudo systemctl daemon-reload
4. sudo systemctl restart snapd.service
and there you go. To be noted that my env has a proxy for http/https and apt.
