UPS Label Error

[Nastassy_XOXO]

I am trying to ship out a package through UPS. HOWEVER, I keep getting the message below. This has never happened to me before, and I am not sure what's going on. Can someone assist? Has anyone dealt with this error?

Did you try contacting the Shopify support? Was the issue solved?
