Here’s what happened. Decided to take advantage of a couple sales Sig was offering. Logged in, got my cart filled, but when I tried to complete the order, it said connection failure. This happened to us on thanksgiving, trying to take advantage of Black Friday sale, but we thought it was due to a huge influx of people online. And just re trying again didn’t help then. Never did get it, they sold out by the time I could call on a business day.
I’ll have to call them Monday, but wondered if anybody else had this happen?

I've had that happen on a couple other websites. I finally figured I'd try a different browser.
That did it. I went back with Edge and it worked.

Probably has something to do with different browser update levels.
It could go back to working when you download browser updates.

My TracFone service does that to me when I use Firefox. I have to use Microsoft Edge to do transactions.

Hmm. Using an iPad, so it’s either using safari, or duck duck go for me. I didn’t try using edge, will have to see if I can go that route.

Well, using EDGE did NOT work. Got a message, something about the gateway connection error, transaction declined. Guess I’ll have to call them Monday. That’s exactly what happened trying to get their Black Friday sale too. And I tried a bunch of time then, which prompted a call from our cc people asking if we had done that. And I’ve ordered things online at other places before and after this with no issues, so I think it has to be Sig.
