nginx serving wrong website under proxy_cache

[Payam Chychi]

have also noticed that requesting to get  to the domain setup for
0.0.0.1 forwards you to one of the domains for 0.0.0.2 or .3

So ive had to turn off caching all together as its 100% related to a
caching issue... im just not sure how to correct it.

Thanks
Payam
