* We are using the latest version of the plugin (2.2.3) and when using curl to
synch to WordPress the result is following:
* ```
504 Gateway Time-out
504 Gateway Time-out
openresty
```
* We noticed that this happens on 2 websites (on different servers, other one is
a single site, other is on multisite). These two websites has lots of users and
content.
* We also tested on that multisite installation with couple of smaller sites and
curl works fine. Any tips how to solve this?

* The synchronization of users require a lot of time. Please check after how long
the 504 error occurs and check if this correlates to any timeout setting of your
upstream server (in Apache e.g. TimeOut or KeepAliveTimeout). You can increase
the according value.
* If you are not able to increase those values, you can use the wp-cli premium
extension to run the synchronization without using HTTP.

* Thank you! We changed timeout settings on the server and this works now.
