System Information
  • Strapi Version: 3.6.5
  • Operating System: windows 10 & server 2019
  • Database: sqlite
  • Node Version: 12.18.2
  • NPM Version: 6.14.5
  • Yarn Version: 1.22.4

I setup an IIS reverse proxy to map localhost to localhost:1337 on a newly created strapi project and everything seemed to be working until I tried to check the “Collection Types”, “Single Types” or “Configure View”.

Collection Types and Configure View do nothing but show a spinning waiting graphic.

I created a new single type with 1 text field named Home. Checking the link goes to:

localhost/admin/plugins/content-manager/singleType/application::home.home

[note: In the following error @localhost/… is actually @http://localhost/… the system wont allow more than 2 links]
but I get an error:

Something went wrong.

I’ve gone thru all of the documentation and tried every configuration suggested to no results.

Everything works if I use localhost:1337 and I am even getting data from the localhost endpoints. I populated fields in Home and checked localhost/home and was returned json. But for whatever reason I cannot get the collection or single types thru the proxy.

Using nginx will complicate things as I am running multiple asp.net sites. There has to be a way to configure the proxy on IIS it’s almost there.

hi @wileyknight have you manage to sort it out? I’m facing the same problem with version 4.0.6 that via localhost:1337 everthing works fine and via the iis site with the host header and reverse proxy i get the" do nothing but show a spinning waiting graphic" when accessing the Content Manager.

Looking forward to your reply.

probebly the solution is to enter in the web.config

<system.web>

 <httpRuntime requestPathInvalidCharacters="" />


    </system.web>

As the error other wise will be “A potentially dangerous Request.Path value was detected from the client”

Hello guys, any news on this topic ? @idc-dev_idc-dev I am so glad you came up with a solution. I wonder how safe it is any clue ?

@leitnermat As long you are using iis purley as a reverse proxy and not mixing with some .net code on that site so I don’t see a problem with that.
If you need protection I don’t think that to count on the asp.net request validation is enough.
