Just ripped out and replaced 0.16.3 with 0.17.1 ... but seeing this after starting ``[netmaker] 2023-01-26 10:02:39 connecting to mq broker at ws://mq:1883 with TLS? false [netmaker] Fatal: Admin: could not connect to broker, token timeout, exiting ... `` And cannot view the new dashboard because: ``Error code: SSL_ERROR_INTERNAL_ERROR_ALERT The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.``
Might be a PEBCAT typo error ... trying again
After fixing typo, dashboard now works ... but I am seeing my old ripped out network in it. And I did a docker system prune before installing again from scratch ... is this normal?

did you include volumes in your system prune? If not, then seeing the old network is expected behaviour

I did a prune -a, but I now had to delete all the volume directories too before proceeding

Ok, thanks
@bored-island-21407 wondering ... can coredns be used for custom dns proxying again?

coredns is only used for extclients

Ok
I have node that Im using for dns resolution, also using coredns. Whenever I create a relay with the netmaker node, for nodes on problematic networks (reason for this is some netclients start to blackhole routes to other nodes), the relayed nodes stop being able to resolve names with the coredns node. Telnet to coredns works, its pingable, etc. Any idea why this could happen?

I'll setup relaying again, one moment
But from old attempts ...
``nslookup google.com 10.254.0.1 Server: 10.254.0.1 Address: 10.254.0.1#53 Non-authoritative answer: Name: google.com Address: 172.217.169.46 Name: google.com Address: 2a00:1450:4009:820::200e ``
This works
Its resolving names behind egress networks that appears to fail
For example: ``nslookup gateway.production.qrios.com 10.254.0.1 Server: 10.254.0.1 Address: 10.254.0.1#53 ** server can't find gateway.production.qrios.com: NXDOMAIN ``
But once I delete the relaying it resumes working
