[miguelmota]

restarting chrome fixed the issue

this is happening to me, and I already restarted chrome. I am trying the Truffle Pet Shop tutorial, have followed all instructions

Same here when getting started with PetShop tutorial.

SOLVED IT: Must enter URL manually as the guide. http://localhost:9545

I still get an endless 'connecting to unknown private network' - any other ideas?

@lonewoolf @Oponn-1

• Just click on on top left menu and select Custom RPC
• In the New RPC URL insert the URL (default: http://127.0.0.1:7545)
• Click Save and click on the left arrow and insert the seed and password

In my case,
set to custom rpc "http://127.0.0.1:2545" -> bug
"http://127.0.0.1:2545/" adding slash at the end. fixes the issue.
at the same time i was opening ganache at the same port. in case it doesn't work.

I too faced a similar issue, in my case it got resolved when I switched to my personal network from my office network, somehow my office network was blocking this.

I got similar issues due to offering more RPC APIs with "--rpcapi eth,web3,admin" when starting up my private eth node, which might violate security constraints of MetaMask.

Wasted some time...

Spinning button does not look like change of the network.

@stefek99 this UI is fixed in #5893, should be released shortly!
