Unable to contact snap store, how solve?

Error: error: unable to contact snap store

I tried all old solution but nothing works and i don’t how can i solve it…

what can i send you to try to solve it?

Does running curl -D- -v https://api.snapcraft.io work? Do you use a proxy in your system? Does not network force the use of a proxy?

I just installed Ubuntu with a bad Firefox snap try to install new failed to connect to snap store. Turned off IP 6 under Wi-Fi as somebody suggested temporarily and it did connect. So that is something to do with IP 6 causing issues, at least in my case.

There was a store outage today, see https://status.snapcraft.io/
