504 Error

I suspect this is a nginx issue. You might check the logs to see what is causing the timeout.

How do I check the logs?

I’m not sure in your environment, you’ll need to check with your hosting company.

Let’s assume that is the problem, how can I try and solve it?

Try checking your site’s error logs for a more specific error message. Your hosts should be able to help you in accessing your site’s error logs.

>Mail Connection Time Out.
The mail server is not responding, but nginx is timing out first giving a slightly misleading error.

You are using gmail so there are a couple of things to check.

1) do you have POP3 access enabled for the email account? By default this is not turned on.

2) does your host allow connections over port 995? GoDaddy and others do not allow this.

Yes, POP is enabled.

I use media temple, as far as I can tell in their KB they support it.

I would check directly with their support department.

Yes, it is supported

Make sure you are using POP3-SSL not POP3.

Well, that’s embarrassing. I had it on POP, silly me.

Thanks for your help and patience! Now I can actually try this thing out!
