Block Explorer URL: https://polygonscan.com/
Troubleshoot Connectivity Issues
Recently the Polygon blockchain has seen unprecedented activity, causing the RPC endpoints to be overloaded. If you are experiencing erratic site loading, transaction delays/failures, or other unexpected behaviour, you may be experiencing an RPC issue.In times of congested networks, consider changing the RPC URL used by MetaMask:
https://polygon-rpc.com/
https://rpc-mainnet.matic.network
https://rpc-mainnet.maticvigil.com
https://rpc-mainnet.matic.quiknode.pro
https://matic-mainnet.chainstacklabs.com
Best way to use is to ensure that you have a dedicated connection from where you access 3rd party providers like Alchemy.com or Infura where you create an account and then create RPC Endpoints and your HTTPS url!
