   > Maybe I encountered the same problem. The reason I found is that our APISIX behind a proxy that responsed for decrypted the TLS and proxied always HTTP scheme to APISIX. let's see the redirect plugin code:
   > 
   > ```lua
   > if conf.http_to_https and ctx.var.scheme == "http" then
   > -- ignore
   > end
   > ```
   > 
   > It will makes the redirect loop apparently.
   > 
   > the resolution is patching this plugin just like:
   > 
   > ```lua
   > local proxy_proto = core.request.header(ctx, "x-forwarded-proto")
   > local _scheme = proxy_proto and proxy_proto or ctx.var.scheme
   > if conf.http_to_https and _scheme == "http" then
   > -- ignore
   > end
   > ```
