Hello NopCommerceTeam,
I'm trying to get Paypals IPN to work but I'm getting nowhere.
I have set up a Sandbox account with two email accounts, one seller and one buyer
I have used PaypalStandard plugin of NopCommerce 2.80 & hosted NopCommerce site at IIS with publicly accessble IP.
In the Sandbox I've tested with the (IPN) Simulator but I always get the same error.IPN delivery failed.
At the first time, IPN works fine but after onwards it gets failed.
Nothing has change on my website yet IPN is being reported as failed. Payments going thru but notification isn't. Anyone know why this is happening?
Can anyone tell why this is happen and how to fix it. I need to fix this immediately.
Any help would be greatly appreciated.
