I got a new firmware version overnight:
You're definitely on an older firmware version than the one I have, this is what I have currently.
I'm on this version:

You beat me to adding that point, camisotro.
While I dont have specific IP reservations just plain set, I do have port forwarding set to my desktop/server.
And Its IP hasnt changed since I set up the forwarding.
So the forwarding does a reservation as well.
Not sure why one would work and not the other then..
My guess is that they borked up the modem's PHP page for setting port forwarding, but the underlying private Rogers-to-modem APIs still work.
Started getting this issue last week on my gateway as well.
go to connected devices on the gateway once logging into it, click the edit button next to my printer, under configuration change the option to Reserved IP, pop in the ip and click save, and it comes back with the reported error, modem details are:
eMTA & DOCSIS Software Version:Prod_19.3_d31 & Prod_19.3
Software Image Name:CGM4140COM_4.6p12s1_PROD_sey
Now i'm on XB7 so this might not apply but i was running into the "Failure! Please check your inputs." error message on the XB7 as well. On the XB7, there is a comments box on the same page to set a reserved IP. All i did was write something in the comments box and it actually saved the reserved IP. after i did an ipconfig /release and ipconfig /renew i had my reserved IP on my PC. Redid it again for my cellphone, turned phone wifi off and back on and it had the reserved IP there.
Hopefully XB6 also has a comment box and we've just been leaving it blank...
