Can't login: getting 'cURL error 6: name lookup timed out'

[camilodelvasto]

Hey,

I was using the service and it was working fine, but then I started getting this error:

Notice: Trying to get property of non-object in /Users/camilodelvasto/Documents/nolte/proposal/wp-content/plugins/auth0/lib/WP_Auth0_LoginManager.php on line 294

THe auth0 log error shows:

WP_Auth0_Api_Client::get_token	http_request_failed	cURL error 6: name lookup timed out

and it doesn't allow me to log in or signup users. What can I do to fix it? Is it something related to my environment? Thanks for any help!

Looks like it is related to your environment.

If you have SSH access in that server, try running curl -v https://your_account_name.auth0.com/testall (replace your_account_name by your account name). It should answer with an ok.

Also, you can check by accessing to the admin (if you add ?wle to the url it will show you the wordpress login form). Then go to the plugin configuration and under the basic tab, check if the domain is the correct one.

Thanks @glena - I'm getting OK on the test, but I'm also seeing something different, perhaps it's related.

When I update the settings, I keep getting an admin notice saying The client id or secret is not valid. - I've checked the settings from my app and that hasn't changed. I've copied them several times and I just get the same notice. Any ideas? Thanks.

[camilodelvasto]

Indeed it was related. I just rotated the secret and now I'm able to log in. Why did this happen?

[camilodelvasto]

After not seeing this error in a while, I'm getting it again... I didn't change anything in the config, and the log shows the same:

WP_Auth0_Api_Client::get_token	http_request_failed	cURL error 6: name lookup timed out

I checked out the auth0 plugin settings and got the same upon save:

The client id or secret is not valid.

Is this related to the wp plugin? Or is it something with the auth0 service?

I'm baffled....

[glena]

the cURL error 6: name lookup timed out looks like there is a timeout during the DNS lookup.

The The client id or secret is not valid. happens when the call to auth0 fails. can you add a var_dump($response);exit; before this line?
I would like to see the response.

Also, can you check if the client_id and domain configured are the correct one?

There is no reason for auth0 to change the client configuration nor the plugin unless there is something on your site changing the configuration (for example, your deploy process restoring the database or something)

[camilodelvasto]

@glena this is what I'm getting from the var_dump($response):

bool(false)

I double-checked the client configuration for the plugin, it all seems correct.... what could be the cause of it? Or better, what else can I do? Thanks a lot for your help @glena

[glena]

so this is checking this: ( 200 !== (int) $response['response']['code'] ). Since $response === false, this is returning null $response['response']['code'] and this casting (int) $response['response']['code'] is returning 0 which is !== 200 (thank you very much PHP).

Do you see any row in the error log (the plugin error log) related to this? You should fine one with the WP_Auth0_Api_Client::get_token section. https://github.com/auth0/wp-auth0/blob/master/lib/WP_Auth0_Api_Client.php#L114

[camilodelvasto]

The weird thing is that I stopped seeing the error altogether.... could it be something with my connection? As soon as I changed the location, the error dissapeared.

[glena]

As I told you, that seems an issue during DNS lookup (unless there is something screwing with the plugin configuration so the domain is an invalid one in that moment). It could be your ISP, the router (or network infra in general), something wrong in the host (configuratoin, something conflicting with the network layer...). that is really weird.
