Caught HTTP Status Code 404, returning error page / 500 Internal Server Error' caused by: unsupported protocol scheme

Traefik Traefik v1
1

Hello,

I got an 'Internal Server Error' with a 404 code ..

I tried to open an issue due to error when I configure custom 404 page

What did you expect to see?

My 404 custom page located in error services when I get a page test.localhost/noexist.html

What did you see instead?

'Internal Server Error' message on response with 404 code .. (no redirect to my custom page)

PS : The catchall works well and redirect to my custom page if virtual host doesn't exist.
