Parity – Cannot Connect from Browser UI

browsersdappsparitysecure-signer

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.

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
