Glad to hear your issue is fixed. Sadly, mine is not.
Upon updating my Balance One to 8.5.4 beta 1, and again updating to 8.5.4 RC1, one of my IOT devices lost connection, and could not be revived by powering it off then back on.
The only solution was to toggle DNS Caching OFF on the peplink, then toggle it back on again.
I reported this extensively with Packet Captures but it seems PepLink can’t fix the bug.
Frustrating - seems like a basic feature like this should work, and bugs should not remain unfixed across multiple versions.
