Paypal won't redirect when trying to bid on auction

[BigDaddyGA]

I've been trying to get auctions setup for an Alzheimer's charity fundraisers for a week now
I've tried the VM Paypal and the PayPal Express plugin. when a bid amount is entered, the number disappears but nothing else happens. no redirect no error
I've tried sandbox and production options:
In VM Paypal i configured standard and express options using PP API, neither worked
In PP Express Checkout: client id and secret setup for production and sandbox

Joomla 3.9.15
PHP 7.2
Valid SSL
VM 3.6.10.10211
Webkul auction plugin 3.0-1.1

This is clearly a case where You should contact Webkul. Paypal is a standard payment that works out of the box with Virtuemart.
