Why because, recently one of client said his application don't fetching any NFTs when user connect his wallet . I checked the code, nothing is changed.. and I tried other provider and its works fine.. then later I discovered this error : {"message":"Method Not Allowed","logref":null,"path":null,"_links":{"self":{"href":"/v2/9rm_U5h0VzHn7r7qdx1YDLUkcIhg2kjH","templated":false,"profile":null,"deprecation":null,"title":null,"hreflang":null,"type":null,"name":null}},"_embedded":{"errors":[{"message":"Method [GET] not allowed for URI [/v2/9rm_U5h0VzHn7r7qdx1YDLUkcIhg2kjH]. Allowed methods: [POST]","logref":null,"path":null,"_links":{},"_embedded":{}}]}} Can anyone explain pls..

we use alchemy solana endpoints for our App, but from yesterday one of the API returns 32000 constantly and it already lasts a few hours. Request: {"id":"291c852a-20ee-4778-94e7-41bc5c2da425","jsonrpc":"2.0","method":"getTokenAccountsByOwner","params":["CG5BkmpYjgatAffeLfMCzhERbxZob5FzqQxTHQjBCwPc",{"programId":"TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA"},{"encoding":"jsonParsed"}]} Response: {"jsonrpc":"2.0","id":"291c852a-20ee-4778-94e7-41bc5c2da425","error":{"code":-32000,"message":"Unable to complete request at this time."}}

We tried using accountSubscribe https://docs.solana.com/developing/clients/jsonrpc-api#accountsubscribe recently with an Alchemy WS endpoint, but we're getting the following error messages (via the established WS connection): ``` {"id":15,"jsonrpc":"2.0","error":{"code":-32601,"message":"Unsupported subscription method: accountSubscribe"}} ``` Similarly for ping messages (-32601 error codes in dashboard).

Do the available Solana nodes have all blocks in it since the genesis block? If not, until what block do they have archived?
