Manually updated firmware, lost access to web interface

[mrdrew]

I’m thinking I flashed the wrong firmware or something?? Is there a way to roll this back? I lost the web gui. It still works! But I get 503 error when I hit the IP for web admin interface.

It was a big jump in versions. I was using the built in “check for firmware updates” and it kept telling me I was on the latest firmware. Then I found the link below. I recall I was maybe on version 3.xxxxxxx

Have you power cycled the RBR OFF for 30 seconds then back ON then try to access the web page? 

Did you first update any RBS to v.31 before updating the RBR? 

Try a Factory Reset as well:
