UPS Rate Quote Issues

[keats76]

I seem to be having a number of issues obtaining UPS rate quotes. About 25% of the time I receive a valid shipping quote and I can process my checkout, the other 75% of the time I receive the "No valid shipping methods" error. At this point I'm starting to think about setting up some flat rate shipping rules because I can't rely on the UPS Online Tools.

Here is a copy of the most recent error in the log:

Error obtaining rate quote for shipping method 'UPS Ground'.

The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.; Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

Does anyone have any experience here? This is quite frustrating.

Thanks,
Mike

We get that error in Able 5.5. Logan put some extra code in Able 5 to check for timeouts and try again so that has decreased the occurences, but it still happens occasionally.

I see it in my event log very infrequently, like 1-2 times a day on a 6,000 visitor a day. I'm certainly not seeing it fail 75% of the time...that sounds like a bandwidth issue.

I get those as well. About the same rate as Joe.

Any chance this is related to the timeout value set in my web.config? I have a rather large timeout set to accommodate large file uploads.

<httpRuntime maxRequestLength="102400" executionTimeout="600"/>

Time to set up some flat rate defaults.

Thanks,
Mike
