Ahoy friends.
Currently i got my OpenWRT device running fine, running OpenWRT on x86 and load-balancing using mwan3. Now i am experiencing some issue since i am using mwan3.
When i try to start Steam downloads, sometimes they do not start, with error code "Connection timed out".
Everything else works fine, browsing and so on.
When i try to check emails on my phone, update the weather forecast, getting eBay notifications, they all do not work, or only get updated when i switch to mobile data.
What is the issue for that, or how can i troubleshoot? Is a DNS issue a possible cause?
EDIT: I got IPv6 enabled as well as IPv6 DNS. Unfortunately IPv6 load balancing is still disabled, can this be a potential issue?
