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": "" }
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.
