I started a clean local state with DFX and spinned NNS and dapp with dfx but, once logged in NNS dapp, the ICP account load forever and I’m unable to get ICP, which basically makes the test setting basically useless.

Can you fix the issue?

```auto
dfx start --clean
dfx extension uninstall nns
dfx extension install nns --version 0.4.1
dfx nns install

```

Open NNS dapp e.g. on [http://qsgjb-riaaa-aaaaa-aaaga-cai.localhost:8080/](http://qsgjb-riaaa-aaaaa-aaaga-cai.localhost:8080/)

Workaround: clean and reinstall the uterrly old version of NNS dapp.

```auto
dfx start --clean
dfx extension uninstall nns
dfx extension install nns
dfx nns install

```

It works for me using dfx v0.20.1, Ubuntu 22.04.4 LTS, Google Chrome Version 126.0.6478.126 (Official Build) (64-bit), and `dfx extension install nns --version 0.4.1`:

For completeness, here’s my `networks.json`:

```auto
$ cat ~/.config/dfx/networks.json 
{ 
  "local": { 
    "bind": "127.0.0.1:8080", 
    "type": "ephemeral", 
    "replica": { 
      "subnet_type": "system"
    } 
  } 
}

Thanks. I cleared the state for the zillion times and this time it worked out here as well. I guess the state went corrupted at some point.

Happened again. Might be because I started and quickly killed `dfx start --clean` - i.e. too slow and parts of the states is deleted but, other parts are still there.

It’s broken again! I definitely did not run any command like `clean` or whatsoever. I don’t know what’s happening, but there is definitely something fishy in that `dfx nns` setup.

Do you see some suspicious replica logs? Some errors in the browser console? Without a way to reproduce the error, it’d be close to impossible to fix it.

It happened again. It feels like every day when I come back to my project, this just crashes.

So, no logs in DFX / local replica, or at least nothing particular.

In the browser console, it’s Xmas:

Note that only NNS dapp and the ledger seems to have issues . My own project deployed with my own canister are just fine. Likewise for II.

Since [http://127.0.0.1:51760/api/v2/status](http://127.0.0.1:51760/api/v2/status) doesn’t work, it looks like the agent is trying to connect to a non-existing replica. Why does the agent not use the HTTP gateway port (8080)?

The replica URL comes from [here](https://github.com/dfinity/dfx-extensions/blob/c09914b15343659e550ee50558b9a8cf8c976312/extensions/nns/src/commands/install.rs#L42) so you should make sure to not stop and start the replica after running `dfx nns install`, or even better pin the replica port:

```auto
$ cat ~/.config/dfx/networks.json 
{ 
  "local": { 
    "bind": "127.0.0.1:8080", 
    "type": "ephemeral", 
    "replica": { 
      "subnet_type": "system",
      "port": 8000
    } 
  } 
}

I’ll also fix the dfx nns extension, but this might take some time to get out, so pinning the replica port is the best short-term mitigation.

I’m not sure I understand what you mean. Are you implying that I should `dfx start`, then `dfx nns install`, and then never stop `dfx` again, otherwise it will lead to the issue?

> [@mraszyk](#):

Sure I can try that.

Don’t worry about the error messages, icx-proxy seems to be too eager, but eventually the connection is established.

Ok, I’ll try again.

Correct. I redeployed. I let know if NNS dapp and its state get corrupted again.
