ER605 doesn't connect/recognize ONU
This afternoon I moved the Omada Controller (docker) from my server to the RPI and everything was working fine, except the router that, once I reseted it in order to be picked up by the other controller, it suddenly stopped recognizing the ONU (mine is just a converter fiber - RJ45), phisically it is connected but on the interface it shows that there is nothing connected to that port, the light on that port blink in patterns, each 2s it blinks two times both on ONU and Router, but just that.
I've tried reseting and connecting it through it's own interface (avoiding Omada Controller), or even downgrading it to an older version (it was at 2.2 but I download 2.1.2 from this forum) but there was no difference, at some point it did detect the ONU, but I was getting "[WAN] of ER605 is down." all the time (not a visual bug, the internet was going down too)...
It's curious that my backup router (Huawei WS5200, provided by my ISP) has the same PPPoE settings (basically only username and password, no fancy things such as virtual ports or specific MAC address) and quickly connects to the ONU and internet. And right now I have it's LAN connected to the WAN on ER605 and it works perfectly, so I don't have the slightest idea of what should I do expect throwing that to the trash.
Another thing, really, why I can't login to the controller when there is no internet connection? It doesn't even make sense. The error message after clicking on Login is "Unable to login, check your network connection" (something like that).
Sorry if I sounded frustrated, I've spent a couple of hours circling around this issue and couldn't get it working.
