Redirect the default /welcome context using nginx

[Dnhatsave]

Helo everyone,

I have a address were a like to host the onlyoffice eg: https://www.example/url .

I look that by default the onlyoffice comes with /welcome context eg: http:my-ip:my-port/welcome
I want to know how can i redirect or rewrite the default (/welcome) context to work at my environment like that: https://www.example/url/welcome

I've tried to use rewrite settings on nginx:

location /welcome/ {
    rewrite ^(.*)$ http://172.31.4.114:28096/colab/welcome/ redirect;
  }

But it gives me 404 Error not found as can you see at screenshoot

I'm not 100% sure because I'm not good with all nginx setup, but I think you need reverse proxy for that

I think all other parts of DocumentServer may be related to that part and if you move only /welcome page - all other URLs that DocumentServer uses will be confused

I'll move this to DocumentServer repo and convert to discussion, since it's not an issue per-se
Maybe someone will be able to help with exact configs

Thanks for replaying @ShockwaveNN ,

I like to know where i can find welcome.html file, what is the path ??
I've do proxy reverse as you suggest but now i want to change the /welcome context for another one.
