[Bug] `Error running 'INADYN_PROVIDER="ipv4@dynv6.com"`

Hello,

Here's my config, my test of the command and the app's output :

$ cat ./inadyn.conf

What to do ?

Thanks

Try running with debug flags enabled to see what goes wrong.

[KaKi87]

Oh I never used command args with Docker, how does that work ? Thanks

Hello ?

[troglobit]

This not a docker support group, try google or the manual perhaps.

I only asked you after trying to find by search without success.

seem same issue here : only IPv4 update though allow-ipv6 = true in inadyn.conf

it seems first guessing is wrong , it's only for ipv4. according to dynv6 API: https://dynv6.com/docs/apis for IPv4-only https://ipv4.dynv6.com/api/update?ipv4=auto

debug : $ sudo inadyn -l debug --foreground --force inadyn[11824]: In-a-dyn version 2.10.0 -- Dynamic DNS update client. inadyn[11824]: Guessing DDNS plugin 'default@ipv4.dynv6.com' from 'dynv6.com' ... inadyn[11824]: Sending alias table update to DDNS server: GET /api/update?ipv4=auto ...

@rpi4iot there has been several fixes to the dynv6 plugin since v2.10.0. It looks like you're running into one of those and not the same as op did. Please try with the latest Inadyn version.
