Wrong credentials with URL

[spamrunny825 0]

Hi guys, 

I don't know if I'm in the good forum, but I'm having a hard time with the Emby Roku app. When it ask for my server, I put my server DNS/URL, I can see my server name, so I put my credentials (I tested mine + a new one I create to try) and it says "Wrong credentials" and in the logs there no mentions of a failed connection or anything. But when I put my IP, now it's working. Problem is the IP changes each time my modem restart so that's why I want to use the URL. Having any thoughts ?
 

Thanks guys !
