Unraid.net and github.com resolve issue (Unraid 6.9.2)

[Aley]

Hello, I installed unraid.net and connect to unraid my server dashboard, retrive https certificate and backup flash, all was ok.

Then i change IP and subnet to connect unraid in his definitive pfsense configuration, now i have a lot of problems 

 

1) Unraid plugins screen say Backup server is active, bash correctly ping github.com but unraid don't find it

2) Graphql is offline, i try to reset api, command run correctly but don't resolve the issue

3) https://forums.unraid.net/my-servers/ don't display my unraid and my address xxxxxx.unraid.net don't go to correct LAN IP, Update DNS button doesn't work

 

My pfsense unraid interface seems ok like other interface, can you help me please??

Can you be more specific about what changed? Was it just the the internal IP of the server or did you also move to pfsense?  pfsense will enable DNS Rebinding by default, so you'll need to disable that for the unraid.net domain.

 

There are two DDNS hosts:
   yourpersonalhash.unraid.net -> this points to your internal IP
   www.yourpersonahash.unraid.net -> this points to your WAN IP

 

What do each of those urls resolve to? I'm guessing the external one is correct, but if the internal one does not resolve at all then you definitely have a DNS rebinding issue.

 

Thanks for providing your diagnostics, are you sure the netmask is correct? It is normally 255.255.255.0, yours is 255.255.255.252

Flashbackup does use git, but it does not use github.com. What makes you think there is an issue with flash backups?

Try going to Apps, Settings - Enable debugging.

 

Then reboot (important), followed by Apps.  Then click on Debugging at bottom left and upload the file here.

Thanks for your reply, i have an hardware pfsense multi eternet:

WAN -> pfsense eth1

LAN  switch -> pfsense eth2 192.168.0.1/25

Unraid -> pfsense eth3 192.168.2.1/30 (no switch, only unraid server)

 

At the first for data move and test my unraid was on lan then i moved on unraid pfsense

 

Today i have roll back to past ip and it's work (i had to add HD and test plex)
Tomorrow i'll try new ip config again and post debug result here, sorry for delay

Thank you!!

Flashbackup does use git, but it does not use github.com. What makes you think there is an issue with flash backups?

 

Hello, unraid was on lan interface on pfsense and the i move it on a dedicated port eth on pfsense (see diagram above)

i use a /30 subnet because i have only pfsense and unraid in this subnet

 

App screen not flashbackup (see image) when i click on App i see a yellow line on the top: "Backup server active...."
i read unraid can't resolve github.com but when i open terminal and ping github.com it resolve whitout problem

I'm using dns forward on pfsense, the same on every port...

 

Tomorrow i'll try again, sorry for delay but i have a lot of work to do today

 

Thank you!

I found the problem, i had a wrong MTU value on pfsense interface!

Now i have to solve only one problem, when open 443 on wan to unraid, i can't access to unraid consolle. I'll do other attemps further...

 

Thnks to all
