Errno

[foxman209]

when I grip，it show me :
[Errno 8] nodename nor servname provided, or not known

[joeyespo]

I wonder if this is caused by utilizing localhost for generating a random port, from

        if port == 0 and open_browser:
            sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            sock.bind(('localhost', 0))
            port = sock.getsockname()[1]
            sock.close()

This and https://stackoverflow.com/questions/39970606/gaierror-errno-8-nodename-nor-servname-provided-or-not-known-with-macos-sie hints at that.

Are you running with port 0 and --browser by chance? If not, could you post the exact command you used and the full output (if there's any more).

Thanks!

I'm getting this as well:

This is on macOS 10.13.5, ZSH, and tested both on Python 2.7.15 and 3.6.5, same results in both. Using pyenv to manage python environments.

Similar problem here.

my ~/.grip/settings.py is just my username and personal access token. This is a new grip instance on my work computer, I'll check my home computer tonight to see if that's also having the issue.

[BenGitsCode]

Has anyone gotten beyond this error before? I'm happy to try some further debugging but I'm not sure where to start with this.

[nikvdp]

@BenGitsCode I had the same issue start happening all of a sudden after doing some work that involved modifying my hosts file. Eventually realized I'd misconfigured my /etc/hosts file and had deleted this line:

127.0.0.1     localhost

Adding that line back into /etc/hosts made grip start working correctly again.

[joeyespo]

Hi, all. Is this still happening? If so, can you try @nikvdp's suggestion?

I can't reproduce, so I'm closing for now. Feel free to re-open if that doesn't work.
