Unable to access some websites even with another network

[badruk]

I can’t manage to access specific websites (namely magic cards specific websites) when I access them via the network of the school I teach in.

I still get problems even if I try to connect to my own hotspot and the only way I can go back to browsing is by rebooting and connecting far from the school (I believe that even if my own wifi is higher in priority something is happening).

If I try to ping the specific website I get “ping: https://www.cardtrader.com/: Name or service not known” so I believe it has something to do with DNS, but I don’t understand how to flush my dns cache (or how that is handled, If I’m not mistaken manjaro’s not using any).

Is there a way to “fix” this “minor” problem?

My Android phone can’t do this, AFAIK - but an IPhone might …:
perhaps your phone is itself connected to the school network?

You could set the connection to not automatically connect - so you don’t rely on the set priority …

wget of the address yields multiple IP' - all of them can be pinged

with right click on the networkmanager icon gets you a context menu where you can switch on/off the network … better than rebooting, perhaps

Although not helpful in solving your actual problem, I think you’ll find ping destinations don’t include the protocol (like https); the command you’d want to try is probably more like:

ping www.cardtrader.com

Possibly your system administrator / it department has imposed restriction on the network.

We cannot help you with such restrictions.

That was the problem. My phone was redirecting the connection through the wifi of the school.

Yeah, I’m kinda dumb.
