Statically set download links?

Server Administration
1

I have changed my port bindings to 8080 and 4343, I am using Nginx as a reverse proxy which works for the landing page. I set up a direct port forward to 4343 to the simple help server thinking that changing the bindings in the admin panel would just generate a client download pointing to 4343…this isn’t the case if I access the landing page and download a client It tries to connect to 443…

What files can I modify to statically set the links to include the 4343 port?
