FQDN address stopped working in local environment.

[pltaylor]

Unraid Version: 16.11.5

Docker Containers : Yes... 20 or so of them... including Swag, PiHole and lots of others that SHOULDN'T effect networking

 

My server has stopped being able to be accessed by the FQDN that is provided by Unraid Connect.  Connect says it can see my server and it is connected, but my FQDN shows as not being able to access the server which is correct, both locally and away from my network.  When I try to connect I get

 

This site can’t be reached

xxxxxxx.unraid.net’s DNS address could not be found. Diagnosing the problem.

DNS_PROBE_POSSIBLE

 

When I try to access https://knownIPAddress I get a 404 not found.

 

I can access docker containers like krusader via knownIPAddress:Port# without problem.

 

I can boot the server up in web GUI mode and it appears to be working well.

 

I have a unifi network with pihole dns turned off for now, just the default DNS setup (It's probably DNS).

 

Does anyone have any suggestions

Is knownIPAddress accessible over http instead of https?

 

Is xxxxxxx.unraid.net resolved if you use a public dns server like https://www.nslookup.io/domains/xxxxxxx.unraid.net/dns-records/

 

[pltaylor]

http://knownIPAddress  redirects to xxxxxxx.unraid.net which can't be reached.

 

https://www.nslookup.io/domains/xxxxxxx.unraid.net/dns-records/ doesn't look like there are any records

I've solved this by going to the Connect settings, regenerating a cert and editing my firewall to let a different port through than I had in the past.

Nice, you essentially did what the blog post recommends and switched from an unraid.net cert to a myunraid.net cert.

 

BTW, I'd recommend installing the Fix Common Problems plugin as it could have alerted you to this

[pltaylor]

I'll be honest, I've been busy so this server has not had the upkeep it has needed to stay fully healthy.  This was one big step in getting it back to where it should be.  The reason I say this is, I have 'Fix Common Problems' installed, if there was a note in there about this it was lost in the other notes that I'm actively addressing
