Hi guys,
Same problem here. Im running Sophos UTM 9, firmware 9.408-4.
If i enable Uplink Balancing, one of my interfaces turn to ERROR (state=UP, link=ERROR). If i disable Uplink Balancing, the interface turn to UP again.
I've tryied to change some settings on Uplink Balancing, but any of them could fix the problem.
Any ideias?
As da_merlin said, on the 'Uplink Balancing' tab, disable 'Automatic monitoring' and add your own Host. I would use Google DNS 8.8.4.4. Any luck with that?
Cheers - Bob
