Cloudron Forum

@rupertsworld you have to disable IPv6 on the server (and not just in Cloudron UI). The Cloudron UI only does not set up AAAA records, does not remove IPv6 on the server as such .

Sounds good.

https://github.com/louislam/uptime-kuma/blob/master/docker/debian-base.dockerfile#L69 installs it upstream .

I have asked internally but Cloudron doesn't send any SNMP metrics and there are no plans either. As for the exporter and tailscale in Cloudron, this is outside our expertise. Besides, we also don't support servers which have other stuff installed since it tends to cause problems during updates. So, I am afraid this is alll quite out of scope

Yes, you can do that . The backup task will be able to handle it.

Maybe I misunderstood the question. You want Cloudron to generate/send SNMP metrics to the exporter which in turn sends it to prometheus which is hosted in your tailscale network?

Can you check docker logs -f mysql as to why mysql is not starting up?

In package com.nextcloud.cloudronapp@5.4.1 it seems to work for me.

Have you tried that command manually? Looks like it hangs. Maybe some mount point issue?

@hakh looks like IPv6 connectivity in your server is not working.

Does ping6 ipv6.api.cloudron.io work for you?

@rupertsworld so DNS resolution is working. You can try ping6 2604:a880:800:10::b66:f001 . It looks like there is some IPv6 networking issue in your server. Maybe you can disable IPv6 altogether and also in Cloudron Network -> IPv6 disable it (then Sync DNS as well to remove the AAAA DNS entries).

Will you then be port forwarding port 443 from the external firewall to the private IP ?

Think it should be ok, this set up is fairly common .

@mmtrade maybe you can create a copy of the files in the mail queue when it dies like this and send it to us?

@mmtrade Are you already on Cloudron 8.3 ? It helps if you have the latest Haraka so that we can debug productively .

If this happens again, can you send a mail to support@cloudron.io and we have to debug it in your instance. It's some Haraka bug . We have to make an issue upstream and possibly provide a patch.

@mmtrade thanks, received . So the issue is that Haraka (the SMTP server) keeps crashing . I suspect this is because the mail queue is corrupt. You can clear it using the commands at https://docs.cloudron.io/email/#haraka-queue-corruption . Can you run the commands there via SSH and let us know if it works after that ?

@mmtrade how large is it? but you can send it to support@cloudron.io . Generally, last 1000 lines or so should be enough .

Can you give us the mail server logs ? You can paste the logs at https://paste.cloudron.io . To get the mail service logs, see https://docs.cloudron.io/services/#logs . There is a screenshot there on how to get the logs. All you have to do is to go to Services and click the logs button next to the mail row.

@mmtrade you need to give a better post title than just URGENT all the time. Several users have already reported you and we have given you enough leeway . But creating URGENT posts is really not helping .

@rupertsworld can you try curl -6 https://ipv6.api.cloudron.io/api/v1/helper/public_ip on the server ? Looks like that fails. Next step is to see if host ipv6.api.cloudron.io works or not.

It should be possible to link up Prometheus and Grafana. Instead of thinking in terms of local IP addresses, just think of them in terms of domain names/services . What issue are you facing linking them (I have no experience in either of these tools, but only with more information is it clear what help is needed)?
