Worked the day before, today 7 Jan cannot connect to Matic MainNet via Metamask wallet on Brave browser. Connect just fine with ETH MainNet. This wallet was working perfectly earlier in the week.
IS MATIC MAIN net experiencing issues?
First of all, never enter the link posted above. It is a scam.
You can change your RPC URL: Network | Polygon Technology | Documentation
Probably your RPC URL is this: https://rpc-mainnet.matic.network , you can change it to this: https://matic-mainnet.chainstacklabs.com
Thank for you the warning and the fix info. Wallet is up and working again.
