What Abdussamad said is correct and since you are using the latest version of Electrum, then I guess the issue is on BitPay’s servers side.

You can wait toll they fix their SSL certificate or just use a bip170 decoder, like the one DaveF suggested, to extract the payment address and the amount to be sent then fill out the send form on Electrum manually.

I have no idea why BitPay insitinsits on using this payment protocol instead of the regular URIs, though!
