What OS are you using? does it work if you run it outside nginx with the same settings?

3

This is interesting, what is your environment?

Could you try our SDK doctor to get more details about your setup, and post its output here?

sdk-doctor diagnose couchbase://localhost/bucket_name
4

also check your SELinux rules, and make sure that nginx worker process allowed to open sockets, because code 13 means permission denied.

For example:

setenforce Permissive
5

thank you its working now but cant store and read documents though I can connect. I will go through the docs and see what can I find.

6

About the sdk-doctor-linux i keep getting permission denied even if i run it in sudo. my environment is centos 6

7

have you tried to put SELinux into permissive mode? It might block access even for root

8 
sudo setenforce Permissive

that made the connection work but what I’m getting is

could you post the server version, and re-run it with TRACE log level?

Could you also try to pass bucket password directly to the openBucket?

<?php
$cluster = new \Couchbase\Cluster("couchbase://localhost");
$cluster->openBucket('bucket_name', 'bucket_password');

couchbase server 4.6.0

you can use github-style code snippets like this

```php
<?php
// some php code
```

or just use CTRL+SHIFT+C to insert four spaces before selected text to make it preformatted.

12

Are you using correct bucket password?

13

sorry and thanks its working now…

<?php
$cluster = new \Couchbase\Cluster("couchbase://localhost");
$cluster->openBucket('bucket_name', 'bucket_password');

instead of my old code worked…
Thanks avsej

so the only difference was in Authenticator? You have probably hit PCBC-471, which will be fixed in next release 2.3.1 (which is going to be published on next week)
