infomaniak IPv6 issues

@Gengar should I use https://www.infomaniak.com/en/hosting/vps-lite ? Can't make out if those have IPv6

@Gengar I have created a ticket now to set the PTR records. But going back to your original issue:
"host -t PTR <ipv6> 127.0.0.150 always fails instantly." This works just fine on my VPS. Maybe you have some firewall rules? I just allowed everything incoming in firewall.

For example I've rebooted my server this morning (like 2 hours ago) beceause my PTR6 was null.
And I've tried again and yeah, I have a communication error during the 1st try that you don't have. But each time it resolve it even with the communication error and the 2nd time it always works. And I have this exact behavior each time.
That's weird.
My firewall is setup like this :

OK, i'm gonna say it: It's something to do with infomaniak, and it's time to move to a different VPS provider.
-
@scooke 🥲 I really like Infomaniak especially their commitment to ecology https://www.infomaniak.com/en/ecology ... If I have no other choices maybe I will switch to another hosting provider... We will see...
@Gengar
Just read the Hetzner page: https://www.hetzner.com/unternehmen/nachhaltigkeit/
If you are looking for an eco-friendly provider, Hetzner is pretty good. -

@BrutalBirdie Oh thanks for the link ! I will read what they do
@Gengar I have a spreadsheet with a bunch of Eco VPS providers here:
I should add Informaniak!
But yeah Hetzner is probably the best option overall imho, great value and great UX. I tried Netcup because they are even cheaper, but 1) you have to pay 6 months in advance (whereas with Hetzner you can just pay for an hour if you cancel), 2) their default Ubuntu is stripped down and so installing Cloudron doesn't work until you mess around installing full Ubuntu first 3) their UI/ UX is just no way near as good as Hetzner's, etc.

@jdaviescoates If it works with Infomaniak, it would be another cheap VPS and ecofriendly one yeah. They have their "VPS Light" that is cheap and atm, except the ptr6 value that switches to null after updates, that seems solid.
With hetzner , can you setup yourself your PTR ? For Infomaniak we need to open a ticket to their support.

Just to say, I used to be with Hetzner and I am now with Netcup and regarding: 1) you do NOT have to pay 6 months in advance (it's just cheaper if you do); 2) I had no such issue with their ubuntu version. I've installed Cloudron from blank ubuntu from Netcup and I've been running several Cloudron instances with no problems. Totally agree with 3), Hetzner UI is SO much better...but then their prices are also significantly higher so I'd rather get better hardware and a lesser friendly UI.
However on my servers, and despite following all the right steps, I kept having issue with IPv6. PTR records and DNS all check OK on Cloudron, MX checks etc, but I keep getting random email bounce from Gmail. The only final solution was to disable IPv6 completely. Perhaps Hetzner is better in that respect.

- you do NOT have to pay 6 months in advance (it's just cheaper if you do)
I'm pretty sure I had to at the time, but perhaps it's just the default and I just missed something during the sign-up process. Or perhaps it was because I was a new customer
(I note that Hetzner makes new customers pre-pay €20 these days too)They refund you if you cancel before 6 months, but I still found it a bit annoying.

I originally had no problem either. But then something changed and I did. But perhaps enough people complained and they changed it back again? Or perhaps you installed your before the change?
I've so far not experienced any IPv6 weirdness nor email issues since I enabled the PTR6 on Hetzner.

My firewall is setup like this :
@Gengar infomaniak set it up today .
My firewall is more permissive than yours. Note that ICMPv6 is probably not included in your firewall. I cannot completely understand infomaniak settings to suggest one way or another. Unlike IPv4, IPv6 requires ICMPv6 and won't work without it.

@girish Ah ! Does it mean the issue is coming from Infomaniak , like from their internal network config ? Or could it be linked to something in Ubuntu that is installed by Infomaniak when we choose Ubuntu 24.04 (like if their ubuntu wasn’t 100% stock image but a bit edited) .
