I deployed an nft collection on solana using metaplex and candymachine. It was working fine for 4-5 days now suddenly I am receiving this error. I was able to connect wallet and mint fine for a couple of days. I am not sure what's wrong now what I am getting 403 from rpc pool?

Uncaught (in promise) Error: failed to get balance of account : Error: 403 Forbidden: {"jsonrpc":"2.0","error":{"code": 403, "message":"Access forbidden, contact your app developer or support@rpcpool.com."}, "id": "" }

    After mailing the support it came to my knowledge that the mainnet-beta RPC owner limited the calls. And since I was using a free rpc pool. I can not do anything about it and have to go for a paid rpc. I just hope it does not require me to re-upload the collection cause it cost sols. And this limitation should be mentioned on solana docs from the start. – Abdulmoiz Ahmer Dec 23 '21 at 11:34

So Metaplex and NFT calls are not allowed on the free RPCs. You'll have to use a paid provider or go with https://api.metaplex.solana.com/

If you're doing any sort of NFT drop, it is still recommended to get a paid RPC.

You shouldn't have to re-upload again, as long as you did successfully on the other RPC.
