Invalid blockhash error when I try to deploy

[Sargnec]

I dont know how to solve this. When I try to deploy to solana with anchor deploy its always gives me this error
Error: Custom: Invalid blockhash
There was a problem deploying: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.

I'm following tutorial made by buildspace and the tutorial name is Build a Web3 app on Solana with React and Rust. I get this error in section 3 lesson 1

I am getting exactly same issue

getting this issue now on a devnet deployment. Interesting bit is i notice it correlating with deployments taking longer. Could it be that larger programs are not being validated in time; hence, the "timeout error" (ExitStatus(unix_wait_status(256)) seems like a timeout error)

I was able to resolve my error by reverting to earlier versions of solana-cli and anchor-cli

solana-cli 1.8.0 (src:4a8ff62a; feat:1813598585)
anchor-cli 0.18.2
rustc 1.57.0 (f1edd0429 2021-11-29)

This is likely not related to Anchor. Closing.

I have solved this in my Linux Mint(Ubuntu):

Local npm package: @project-serum/anchor 0.20.1
Solana program dependencies: anchor-lang 0.20.1, anchor-spl 0.20.1, solana-program 1.9.4
deployment to devnet failed

Local npm package: @project-serum/anchor 0.18.2
Solana program dependencies: anchor-lang 0.18.2, anchor-spl 0.18.2, solana-program 1.9.4
deployment to devnet succeeded!

in both cases, the global environment is:

Rust 1.57.0
solana-cli 1.9.4
@project-serum/anchor-cli 0.20.1

For Mac M1,

Rust 1.57.0
solana-cli 1.8.0
@project-serum/anchor-cli 0.20.1

these tools' versions work.
I tried myself.

Reverting solana-cli from 1.9.5 to 1.8.0 fixed this for me

@abhi3700 @jeffhu1 did u have issues compiling solana 1.8.0 on M1 mac?

i'm getting

solana-cli 1.8.12 works

One main reason for this error is poor internet connection, make sure your internet connection is fast enough before deploying.
