In many versions, back to CPS 6 it seems, they always had a read only web client:

I have had several doctors over the years who use Apple products and a few of them got by while on call with this because it was easier to get to then a VPN+RDP, especially on an iPad.
I am not sure if it moved or has been eliminated but I no longer see it available. Just curious if anyone else uses it. I understand that it is not very useful but it proved very helpful in at least two cases that I recall. It has not changed at all but they included it up to version 12.3.3. It might be on V19 but I haven't checked. It has always worked so there really was no support necessary and most people at GE support didn't even know about it when it came up in conversation.

Never used it, but I found ours on 12.3.3 and its working. The url may be slightly different, maybe you renamed your database?
http://[servername]:9080/[dbname]/emrgwt/Emr.html#Login
It is a new lab server I just set up. It works fine on my 12.3.3 server and that URL has never changed for many years, besides the servername and dbname as you noted.
It's being replaced with something they are calling the C-Now web interface and it is cloud based. It's called Centricity-Now in v19 and C-Now in v20. When I was at the University of Oklahoma, we used the read only client as our fail-over for access if our Citrix Farm ever had access/availability issues.
