Blockscout: Blockscout cant connect to Parity - WS Error <Http(Token)>: Invalid byte where token is required.
Blockscout cannot seem to connect to local Parity to read Ethereum mainnet block data.
Environment
Ubuntu 16
All prerequisites exactly as per install procedure
Parity-Ethereum/v2.0.4-beta-e2e1d22-20180910/x86_64-linux-gnu/rustc1.28.0
Indexer config
use Mix.Config

]
]
Steps to reproduce
I have an ethereum main net Parity running on the same machine as blockscout. For the purposes of trouble shooting this, parity is launched with the following unsecured parameters - exposing api etc to everyone.
Start parity with:
parity --jsonrpc-cors all --ws-origins all --ws-hosts all --ws-interface all --jsonrpc-interface all --unsafe-expose --jsonrpc-apis all --ui-no-validation --ui-interface 0.0.0.0
Fresh build of Blockscout
mix phx.server
Expected behaviour
Blockscout should start and operate same style as POS but with Ethereum blockchain data.
Actual behaviour
The Parity terminal outputs this error shortly after mix phx.server is started
2018-09-19 22:46:32 WS Error <Http(Token)>: Invalid byte where token is required.

22:24:42.286 application=plug [error] Cowboy returned 400 and there are no headers in the connection.
This may happen if Cowboy is unable to parse the request headers,
for example, because there are too many headers or the header name
or value are too large (such as a large cookie).
You can customize those values when configuring your http/https
server. The configuration option and default values are shown below:
protocol_options: [
max_header_name_length: 64,
max_header_value_length: 4096,
max_headers: 100
]
*Tell us what happens instead.*
If it helps, here's the headers when trying to connect to websocket

@ImrieA It doesn't look like you have tracing enabled on your node. I'll attempt to replicate over the next few days.

Thanks @acravenho , tracing is on . But looks like I didn't realize Parity starts with pruning by default these days... After disabling that it shows blocks in the Blockscout explorer but the WS error in the subject of this issue still remains.
```
nano ~/.local/share/io.parity.ethereum/chains/ethereum/user_defaults
{"is_first_launch":false,"pruning":"archive","tracing":true,"fat_db":false,"mode":"active"}
```

Here's the output after disabling pruning. It seems to have properly indexed a few thousand blocks and stopped. Now whenever I start the explorer it outputs the below
mix phx.server

@acravenho
Both these files are empty
ImrieA
on 21 Sep 2018
@ImrieA It's 100% a node issue. I should have some time this weekend to provide the exact settings to configure for your node. We've had many changes over the last couple months to our nodes but this is something we need to provide better documentation for.

I've experienced the same issue with the WS Error <Http(Token)>: Invalid byte where token is required..
rsoutar
on 26 Sep 2018
yeah i had a working block scout but now it seems to be broken since now im getting the same error may be due to a new parity version since i started having issues after i swapped my parity. its due to the websocket wanting the token output by the command parity signer new-token i have yet to find a way to disable it. im going to try to backdate and see if that helps
Alaradia
on 26 Sep 2018
@Alaradia What Parity version did you upgrade to? We have compatibility with < 1.11. We have not yet tested 2.0
acravenho
on 26 Sep 2018
yeah i went from a version im not sure what it was to 2 so that's probably the issue ill try 1.11.
Alaradia
on 26 Sep 2018
@rsoutar @Alaradia Thanks for the help with this issue. I've created a new issue #818 for our teams to tackle in the next couple weeks. I'm going to close this issue for now and will reopen once we have full support for Parity 2.0 and this is not resolved.
acravenho
on 26 Sep 2018
i tried 1.11.1 and same error not sure if theirs some weird issue going on with some sort of system flag not stored in parity's directory im going to try nuking my test environment tomorrow and see if i can reproduce on a fresh install
Alaradia
on 26 Sep 2018
Sounds good. Please keep us updated :+1:
