@girish Okay so here it doesn't work the same. 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. [image: 1743246186030-9ef21f71-8c5e-412e-b08c-70567c13b7ac-image.png] That's weird. My firewall is setup like this : [image: 1743246292120-13a01790-02ca-4abd-a067-395cdc10e47f-image-resized.png]

This is fixed in the new UI for Cloudron 9

Usually, the issue here is that the SFTP service is not running . Services -> SFTP -> Restart maybe?

Which version of Cloudron are you on? You will get a full trace at /home/yellowtent/platformdata/logs/tasks/8216.log

Hear Hear! Thanks a lot

@nebulon well no, not generated, how it is extracted is where the error comes in, right?

Looks like Cloudflare is interfering here and changing the data in transit? You would have to contact Cloudflare about this, but I have no high hopes that this would get anywhere.

Thx for the hint. Will see what Hetzner support has to say.

wohoo. cloudron-support --recreate-docker solved the problem.

@SamGreenwood I would run the troubleshooting tool for a start - https://docs.cloudron.io/troubleshooting/#troubleshooting-tool

Just recheck... and I can do this. Was 100% it was not possible. Might have been an "between my ears" problem, sry

@avatar1024 sadly, the docs search is not the best It really needs some a natural language component to it (we are building one, just very low priority)

@mmtrade see https://docs.cloudron.io/email/#outbound-ports . you have to set up a relay . your VPS provider has blocked port 25.

@wmlutz said in Outbound SMTP (Transactional Email) Stopped Working - Invalid login: 535 Authentication failed: @jdaviescoates got it! It was the IP allowlist. Glad to be of assistance @wmlutz said in Outbound SMTP (Transactional Email) Stopped Working - Invalid login: 535 Authentication failed: mailgun's transactional email cost which is cents/mo. I don't think I've ever paid anything yet as I've not yet gone over the 1000 free messages a month or whatever it is...

@girish No OOM errors seen. They often barely get close to the memory limit too. It's usually only about 15-30% usage for the memory for the redis containers. I looked at dmesg but do not see anything yet. I'll take a look when It happens again. Interestingly though, I do see a similar issue with the Graphite service too which I filed a separate report for in case they're different. The main difference to me is that it doesn't block the backup process so it's less of a blocker for me at the moment, but something that should still get resolved.

@potemkin_ai said in can't install cloudron due to unbound issues: It seems like unbound is only used for SpamHause and during setup. If the setup issue will resorted, only SpamHause issue will remain. It's also used for DNS propagation checks (during app install, change location etc) and also verify validity of DNS records for Let's Encrypt. We cannot rely on caching resolvers because they would cache not found (NXDOMAIN) entries for very long periods of time. The recommendation is to keep all the outbound ports open - https://docs.cloudron.io/security/#outbound-ports .
