I've started getting these errors about 2 weeks back. No config change on the system.

I've had a few of these recently too. From the error it seems that Safeway's DNS entry wouldn't resolve. Is the error still occurring for you?

Hi, I know this issue is ~18 months old but I wanted to check in again. The specific issue in your second reply appears to be in retrieving the preferred store ID for the Your Club Specials offers. That feature appears to be removed from Safeway's site so I have removed the related code in 095f7c2.

I checked my own logs and I only see two similar network-related errors from the past year or so. ON my end, these appear to be transient network issues.

Let me know if you're still seeing these errors and I can dig in a little more.

I haven't seen this issue again since I last posted. I'm closing this ticket. Please reopen it if the issue returns.
