Can't connect to ISP PPPoE after drop/restart/power out

RouterOS General
1

Hello, I have a Mikrotik Hex that I use to connect to my ISP DU EITC (Emirates Integrated Telecommunications Company) via PPPoE connection. The Mikrotik Hex is connected to the ONT GPON, which is configured to bridge mode.

I am facing a major problem whenever the PPPoE connection drops for whatever reason, power outage, Mikrotik reboot / update / reset / power outage etc. When this occurs it takes between 6 minutes to hours for the PPPoE connection to re-establish.

I tested the PPPoE connection using my PC directly to the ONT, an Airport Extreme router, and each time the PPPoE connection was dropped manually I was able to reconnect without issues.

So the only device facing issues with the PPPoE connection is the Mikrotik. Can someone please help me with a fix to this issue? What configuration can I do for my mikrotik to stop this problem?

It might seem like the ISP equipment did not like the way the Mikrotik closed the PPPoE connection? which consequently resulted in a PPPoE session already active? The other devices I tested didn’t face this issue so I am certain now its a problem unique to the Mikrotik, and I am looking for a fix.

Many thanks!

Restarted my Mikrotik Hex a while ago and the PPPoE connection took around 20 minutes to re-establish.
The following message kept repeating in the log for 20 minutes until the PPPoE connection was restored, sometimes it takes 6 hours.

pppoe-out1: connecting…

pppoe-out1: terminating…

pppoe-out1: disconnected

Please help me out if there is any way to troubleshoot and fix this problem?

Kind Regards

It maybe an ISP problem, but I have same problem with PPPoE over fiber, with Huawei ONT (in bridge mode). I put the ONT and the Mikrotik behind an UPS,
My ISP is Digi (yet, under acquisitions with other ISP-s), Hungary.

Thanks for adding your feedback to this common issue.

Another case with same issue with Mikrotik https://www.reddit.com/r/mikrotik/comments/14buf3j/the_router_cannot_restore_the_pppoe_connection/?utm_source=share&utm_medium=web2x&context=3

I was hoping someone from the forums could guide with instructions on what to log and what to look for that could pin-point the problem with the PPPoE connection not reconnecting after the session is dropped. When I called the ISP, they asked me to connect the PC to the ONT, and performed multiple PPPoE disconnects + reconnects at the same time and they all worked.
