Os error while deploying asset canister

Hey, does anybody know why i get this error while trying to update my already existing asset canister(Frontend)?

Error: Failed while trying to deploy canisters.
Caused by: Failed while trying to deploy canisters.
  Failed while trying to install all canisters.
    Failed to install wasm module to canister 'AppicFrontend'.
      An error happened during communication with the replica: error sending request for url (https://icp0.io/api/v2/canister/dduc6-3yaaa-aaaal-ai63a-cai/read_state): error trying to connect: tcp connect error: Connection refused (os error 111)

What dfx version are you using?

I use version 0.19.0

Can you please try to update to 0.20.0? Some users did report this error and it should have been fixed on 0.20.0.

Thanks, it was due to the DFX version, after update it started to work.
