Recently I have started getting an error 404 for add to cart link:
/checkout/cart/add/uenc/…../product/1432/
when clicked in product view page. In category view all is fine. It seems like it is related to varnish cache as when I switch back to built in cache: redis, everything is fine.
When checking log using: varnishlog -q ‘ReqURL ~ “/checkout/cart/add/uenc/”‘

And when I check link locally, using curl:
curl -I
http://127.0.0.1:8080/checkout/cart/add/uenc/aHR0cHM6Ly96b3J6ZWNob3dvb3d5LWJpby00N2c/product/2488/
I receive HTTP/1.1 302 Found redirection to https…
I use customized varnish config but an issue is still there when default varnish config is in use and most often mobile view in chrome is affected.
I don’t know exactly when this error did start showing up, so I can’t find a root cause. Any ideas?
