i set up ups access key, user name and password also requested production access.
But when i estimate shipping charge and it always response
"UPS Service is currently unavailable, try again later. Unable to connect to the remote server"
i am using Nopcommerce 3.9 and Nop-Template Tiffany.
Anyone knows what i miss?
Thanks in advance!
Unless you are just unlucky enough to be setting it up just when UPS API happens to be down (which I doubt), ....
Try: Call or email UPS support and tell them to switch your account to a live account (production).
Also, check your server's network / firewalls, etc. It's possible something is blocking your outbound https request.
thank you very much for the suggestion!
UPS switches to live account already (i have checked it).
i use my own windows reseller hosting. i have another site encounters same problem with USPS setting.
i guess it's my Plesk windows service plan configuration causes this problem.
still looking for the solution.
