IPv6 is broken after Update to 23.1.4 + 503 Service unavailable error

[PhoenixRider]

Hello,

i have updated my OPNsense to version 23.1.4 und now the clients cannot assign an IPv6-address anymore. The OPNsense interfaces itselfs have an IPv6 address, but the clients don't get an IPv6 address. I guess there es a problem with DHCPv6.

I also receive a 503 Service Unavailable Error Message when i connect to my opnsense. A revert to version 23.1.3 fix my problems successfully.

It seems like, that the clients don't gets the IPv6 Default Gateway. Maybe this is the problem?

I think its fantastic they push out update after update say they solved problems but in
all updates they fix problems, they also destroy things that working, how should it be
if you do some testing before push out update. Now there is more problems with IPV6
Client dont get any IP, You dont get any prefix from provider.......
With all your respect i really dont understand this.

Now i have updated to version 23.1.4 several times. And now my clients gets an IPv6 address, but now i receive 503 Service unavailable error and can't connect to my opnsense via webinterface. Please fix the problems.

My ipv6 works fine.
Maybe you could try restarting the radvd service? That is what provides the default gateway.

I get furthermore 503er error messages. Via SSH i have tried to restart all services, but it doesn't helped. I will revert to version 23.1.3.

[IsaacFL]

Did you try rebooting?

[PhoenixRider]

Yes, serveral times

[IsaacFL]

Are you using ULAs or VIPs

[PhoenixRider]

ULAs only. I don't have changed the IPv6-settings. Version 23.1.3 runs absolutely fine and without 503 error.

[IsaacFL]

My ipv6 is having having problems too.  It seems related somehow to radvd and VIPs

[PhoenixRider]

Did you revert back to version 23.1.3? Runs with the latest version all fine? In any case something is wrong with version 23.1.4.

[IsaacFL]

Im still on 23.1.4.  trying to debug first.

[IsaacFL]

Where are you see the 503 Service unavailable error.

radvd is definitely broke.

Only, if i want to connect to the opnsense webui.
