Ref.: #34243
Background/Details:
When the Peplink router uses DoH (e.g., NextDNS) as the DNS service and the DNS Proxy service is enabled, DNS resolution may occasionally stop working, causing clients to experience DNS request timeout errors.
This is a DNS service component issue and it has been fixed in special firmware 8.5.2s049. The fix has been added to the 8.5.3 GA firmware release.
Affected firmware version:
8.5.2 GA
Affected models:*
All Models (Except FusionHub)
Fixed in firmware version:
8.5.2s049
