Issue I can't upgrade Plesk. Unable to connect to autoinstall.plesk.com

[aless]

Hello,

I am experiencing technical difficulties using the autoinstaller, which cannot complete the upgrade process.

I tried these solutions already, but none solved
https://kb.plesk.com/en/9283
https://kb.plesk.com/en/113175

Running the autoinstaller via SSH with "/usr/local/psa/admin/sbin/autoinstaller" didn't help. It gets stuck while trying downloading products.info3. It seems my server is unable to connect to autoinstall.plesk.com. I can reach the destination from the browser though.

Currently there isn't any autoinstaller running process, and apparmor is disabled.

How could I solve the issue? Failed upgrades are resulting in a huge loss of performance. Please help.

Thanks.
All the best,
alex

Your server can connect to another sites? Try to connect to google, etc to see if you can reach them. If yes, then is an issue with connection to PLESK servers, if not, then your server have an issue with external connection, then you need to fix that.

Thanks for your reply.

You might be right, it seems I can't telnet google.com on port 80. Connection refused by foreign host. Nevertheless, I could connect to the mirror servers for updates using apt-get update (all except plesk), and iptables allows connections on http port.

Do you have any suggestions about what I could investigate further in order to solve this annoying issue? I don't understand what keeps going wrong with the upgrade. Until two days ago there were absolutely no problems.

Thanks. And best,
alessandro

I am not very good in networking part, but I would start with check firewall (stop it) then retest, if still is same, then can be /etc/hosts file modified, corrupted or other issues what I cannot forsee. Try also to check log files /var/log/messages ?

 

[aless]

Unfortunately same result with firewall disabled
/etc/init.d/psa-firewall stop

In etc/host file I have this lines
199.115.104.31 pleskwin.download.swsoft.com download1.parallels.com autoinstall.plesk.com origin.autoinstall.plesk.com
according to this tutorial https://kb.plesk.com/en/113175

Any other ideas?

Thanks,
alessandro

Your /etc/hosts file should be cleaned up, in order to be of the format:

127.0.0.1 localhost.localdomain localhost
<server IP> <server FQDN hostname> <server shortname - optional>

and just replace the variables in <> to contain the relevant values.

This implies that the line

199.115.104.31 pleskwin.download.swsoft.com download1.parallels.com autoinstall.plesk.com origin.autoinstall.plesk.com

can be removed completely.

It is very, very likely that the above mentioned line is causing many issues, including the issue you encountered at the moment.

Hope the above helps, just let me know.

Regards
