Hi

I have a magento installation, with multiple stores around 40 stores.
I have varnish setup and its working.
But for some reason yesterday, a problems have started showing up.

That 3 store is gettting this error:
An error has happened during application run. See exception log for details.

But nothing in the exception.log in pub/var/log/exception.log about this store.

I have then changed so that these tree shops are running without the proxy varnish setup, and now there are working.

So for some reason varnish, have an issue with just these 3 stores.
It have work before yesterday, just fine.

But no matter in whitch log file i look into, i can't see why varnish is showing that error message, when just access these 3 stores.

Have anyone any idea where to start looking for this?
