Unable to login to EMBY after latest QNAP NAS firmware update

[Danno 2]

Thanks everyone. I did get it to finally work. 

I actually have two NAS devices (Terramaster and QNAP).  I had EMBY running fine on my Terramaster (my backup NAS) using a username (upper and lowercase) I thought was correct.  But I think the QNAP had the same username but only UPPERCASE. I couldn't log in with either on the QNAP.  Both NAS's have dual LAN ports.  I re-installed EMBY on the QNAP.

I don't understand networking enough, but I just noticed my QNAP Emby shows my in-home access on one port and the QNAP homepage I access is on the other port.  

Ultimately, I was able to create a new instance of EMBY on the QNAP and used my upper/lower case userid and it worked!

Many thanks to the Emby community and tech-support.
