SFTP port 222 not working, Firewall UFW was inactive
-
For a start, Cloudron is not using UFW to configure iptables but uses iptables directly, so you should disable UFW again.
Now then try to run
systemctl restart cloudron-firewallto reconfigure iptables for Cloudron. This should restore the iptables rules. -

I have disabled UFW and I ransystemctl restart cloudron-firewallNext, I checked if port 222 is open:

@robi Is this what you mean? I'm not so well versed with iptables.

The SFTP service is run in a container, so the iptable rules are managed by docker. If you do
iptables --numeric -L DOCKER, you will see them in the input chain'sDOCKERchain:Chain DOCKER (2 references) target prot opt source destination ACCEPT tcp -- 0.0.0.0/0 172.18.0.6 tcp dpt:8000 ACCEPT tcp -- 0.0.0.0/0 172.18.0.6 tcp dpt:2004 ACCEPT tcp -- 0.0.0.0/0 172.18.0.6 tcp dpt:2003 ACCEPT tcp -- 0.0.0.0/0 172.18.0.7 tcp dpt:22 ACCEPT tcp -- 0.0.0.0/0 172.18.19.175 tcp dpt:7494The
dpt:22rule is the SFTP rule. We expose port 22 in thesftpcontainer as port 222 to outside world. You will find the translation as a NAT rule.

Also, you must ideally not enable
ufw. Docker manages iptable rules and ufw and docker don't work together (meaning, both tools are unaware of each other's existence, so you have to be very careful when updating rules).ufw also does not remove the rules when it gets disabled. The only way I know to remove all those ufw rules is by rebooting the server.
Finally, about your SFTP issue, can you please check if the SFTP service is running ? If you find the above rules missing in your iptables altogether, this is a sign that the container itself is not running (for whatever reason). If the rules are listed, then it means the SFTP service is not running properly internally. There was an issue that we saw the other day where the sftp service has errors related to SFTP key permissions. Can you please check the logs in Services -> SFTP -> logs ?

Yes, this is the issue! So, what you have to do is:
chmod 600 /home/yellowtent/platformdata/sftp/ssh/ssh_host_rsa_keyThen, just restart the SFTP service. Can you let me know if that works?

@scooke it was fresh, I only setup my ssh and followed exactly whatever was in the docs, the end result of the migration was very smooth, no problems at all. I have never tried any SFTP prior to the migration so I would not be sure.

I suspect we have a bug in our migration+sftp permissions. I will investigate. The private key is restored with group readable permissions, so the sftp service refuses to start.

YESSS!! It works! Thank you so much @girish
Amazing. Yep, now I've connected to my sftp.
I also use my ip address for the host, instead of my.domain.com because I use Cloudflare. (referring to the doc) -

@girish yup, I think that's it. Worthwhile to put that in the docs for now, just in case somebody searching for a solution quickly (if they don't find this post).
