Cloudron Forum

I've just ran into the same issue, would be awesome to have this option !

Hello everyone,

I'm new to this forum (and to Cloudron) and wanted to share that I'm also having issues with IPv6, specifically the PTR6 record.

For some reason, my PTR6 record is in a non-working state (red) and shows a null value.
BUT, I found a workaround.: Rebooting the server.
It temporarily fixes the issue, but after approximatly 12 to 48 hours, the PTR6 record turns red again.

I’m not sure why this happens, but I think it might be linked to the IPv6 issues discussed in this thread. My PTR6 record is correctly set on my VPN provider’s side, so the issue seems to come from either Cloudron or Ubuntu 24.04.

Interestingly, when I check with MXToolbox, the PTR6 record has the correct value, even though Cloudron reports it as null.

My VPS provider has two name servers, and I noticed that MXToolbox retrieves the PTR4 record from the first NS and the PTR6 record from the second NS. This shouldn't normally cause any issues, but I’m mentioning it just in case it’s relevant.

After rebooting my server, everything is green again and working as expected. Both Cloudron and MXToolbox now show the correct PTR6 record. Interestingly, this time, the PTR6 response is coming from the first NS instead of the second (in MXToolBox). No idea if there could be a link with cloudron getting a null value maybe when ptr4 and ptr6 answers are note coming from the same NS server ? … ‍️ Yeahh naaah it seems too weird. Shouldn't be the case.

Has anyone else experienced this? Any ideas for a more permanent solution?

Thanks!

@joseph When I have the issue ? Or when I don't ? As I already rebooted my server a few hours ago, atm I don't have the issue. But I guess it will come tomorrow or the day after.
