why are you proxying your requests?

GonzaOP•11mo ago

becouse i have multiple apps that render after certains conditions

Brody•11mo ago

well one of those errors has a completely different hostname, is that normal?

GonzaOP•11mo ago

its another app

Brody•11mo ago

Brody•11mo ago

if you're on slim you won't need that alpine variable that's only when you use an alpine image
