I am not able to connect to Parity via the browser UI. I have tried multiple times with different tokens generated by running the command parity signer new-token on the node where parity is running. But the response in the browser is always the same:

Unable to make a connection to the Parity Secure API. To update your secure token or to generate a new one, run parity signer new-token and supply the token below

On the node console, I see the following message, every time with different numbers on the first line. The first number is always less than the second one:

Received old authentication request. (1486765366 vs 1486765433) Unauthorized connection to Signer API blocked.

Parity version: Parity/v1.6.0-nightly-afa1edb-20170125/x86_64-linux-gnu/rustc1.14.0

Any help is greatly appreciated.

  • I found this github.com/ethcore/parity/wiki/UI-Remote-Access that says that the team's main focus is for the UI to work locally. I am trying to access it remotely, and I just checked that my client machine's time is not in sync with time.is which, as the doc says, is required. Have not tested whether fixing this gets rid of the error. Will post if it does.

The problem is fixed now. As I mentioned in my comment under my question, the root cause was the big time difference of 1 minute and 7 seconds between my machine and https://time.is. My machine had not been able to connect to our internal time servers due to an internal issue, so had fallen behind. Once the time was sync'ed, I was able to connect via the ui interface.

This is the doc that helped me fix this: https://github.com/ethcore/parity/wiki/UI-Remote-Access

I've come across this issue before and I've solved it by following these steps:

  • Stop Parity
  • Rename the key file in Parity/Ethereum/network to __key.
  • Start Parity

  • Thanks, but I tried that and it didn't work for me. Specifically, I still get the same error messages in browser and on the node. There must be something different in my configuration.

  • Hmm, that's interesting. Does Parity create a new key file?

You can make open it by starting the node with interface IP parameters:

$ parity --dapps-interface <IP> --ui-interface <IP>

But make sure you really want this. You could also test the functionality of --dapps-user and --dapps-password to increase the security.

  • Are those command line options equivalent to having sections [dapps] and [ui] with interface and port specified for both, in the TOML config file, and then starting the node with $ parity --config <configfile>? That is how the node was started.

  • Yes that should be equivalent.
