UPDATE – The issue below is resolved in hotfix 3.00.242.
In our latest release, we have converted to eBay’s newer token authorization scheme. This has worked fine during the beta, but now that more people are using it, it seems to be triggering some errors at eBay. We believe it is stretching the bounds of their servers. The errors are hit and miss. Some users don’t see the errors, others will get the errors sometimes, but work fine other times.
Users may see one of the following errors as a result:
– IAF Token Supplied Invalid Error
– IAF token supplied is invalid
– Unable to write data to the transport connection. An existing connection was forcibly closed by the remote host
– Error: No response from eBay
As a result, we are in the process of reverting back to the original token authorization scheme and will be releasing a hotfix soon. We appreciate your patience and want you to know that we are working quickly to get this resolved.
