@skeal did you solved this? I have the same problem.
Stops to "mounting skynet web page.." after that dead silent log.
I will call @Adamm and @cmkelley is this problem caused by scribe?
Once skynet opened from AMTM then log continues to populate again:
installer adds Bootstrap DNS servers in wrong format. "Error: control/dns_config | [1.1.1.1 1.0.0.1] can not be used as bootstrap dns cause: invalid bootstrap server address: Resolver [1.1.1.1 1.0.0.1] is not eligible to be a bootstrap DNS server | 400"
I have exactly the same behavior with my RT-AC86U router and 386.3_2 FW. Have been long time. Also sometimes client list freeze totally, and not updating disconnect / connected devices.
